The rotor rebuilding or replacement takes care of the clock's problems about 80% of the time. Shipping for an individual rotor or coil or together is the same $15.00. Complete rotor rebuilding information is located at: http://www.telechron.us/rotor.html If your Revere or Herschede clock is a chimer, meaning that it does chime each quarter hour and strikes the hour, then it would take a "B-3" rotor. This includes Grandfather and Grandmother and many mantel clocks. Rebuilding your "B-3" rotor costs $150.00. Unfortunately many old Revere and Herschede chiming electric clocks have had the rotor replaced prior and therefore will not contain original parts. I can restore to originality or can repair what is currently there, your choice. Another problem area is the coil. In all cases the clock has a coil and if needed that is $100.00. These are most always 4 watt's. 4 watt coils cost $100.00. About 5% of clock problems has to do with the coil. To determine whether or not you need a coil, you can take a Multimeter or Volt/Ohm meter, these are less than $10.00 at any hardware store, and with no current on the motor, set the meter to Ohms and touch the two leads to the end of the wires or the posts where the wires connect and see if you get a reading. Just about any reading is a good one and if you can see the coil #, that represents the Ohm reading so if your coil is a # 60 coil then you should get about 60 or 600 ohms depending on the setting of the meter. Some have indicated to me a fear of the clock shorting out or becoming a fire hazard. If that's the case then purchase a power strip and only plug the clock into it. This way you have a fuse to stop an overload before it feeds back into your household or office wiring. Honestly, I have never heard of an electric clock causing a fire but putting in a power strip may ease some fears. For non Telechron "motored" clocks, then the service would be for a clock motor and that can be handled as well, with motor rebuilding costing $150.00 with all else staying the same. I do accept the movement (mechanism) for electric Grandfather and Grandmother clocks but, most likely, you would need an expert to install it once it return to your located or the location of your clock person. Please be aware that both Revere and Herschede used the "B-2" rotor initially. After a few years they both realized that the "B-2" did not have enough torque in order to last more that a few years or decades. First they tried increasing the wattage to 4 watts and eventually went to the "B-3" rotor. Therefore, I strongly suggest that your "B-2" rotor be replaced with a "B-3" rotor, as was done at the factory, especially if you send in a movement used in a Grandfather or Grandmother electric clock. Please be sure to double box the clock and insure it for at least $200. By double box I mean to pack the 1st and 2nd boxes as if you were going to ship each independent from the other one. I use a 24" x 9" x 9" as the first box and then use a 28" X 12" x 12" box for the second. Eco Box is an on-line business in Texas that allows you to order as little as one box. So if you're having difficult securing the correct size boxes, then you have another resource. Please remove and include the pendulum if the clock has one, most electrics do not have a pendulum so don't knock yourself out trying to find one. Old parts are returned by request only. My turnaround is 4 to 6 weeks for motor/rotor service, 3 to 4 months if the clock is sent with the motor/rotor, and 6 to 8 months for a movement overhaul and expedited service adds $100.00 and if you choose expedite and I cannot return a working motor then the $100.00 is still due and all work is done in Clinic. Expedited service take about 2 weeks for motor/rotor service, one month if the clock is sent with motor/rotor, or the movement needs to be overhauled. The movement will tell me if it needs work once the rotor rebuilding is finished and I always clean and lubricate the movement before testing starts, so as to eliminate dirt and a lack of lubrication from preventing the clock functioning properly. Your problem could also be the caused by wear in the movement (mechanism) from usage. About 15% of the time this is necessary and this would require an overhaul. An overhaul on chiming electrics is $500.00 plus $50.00 shipping. The movement overhaul does NOT include the rotor or coil, so that would be added to the cost of the overhaul and that would be the worse case scenario. I realize this may all be confusing but I never do more than is needed and the clock always stays original, as sent to me, or I refuse the work.
Here's a possible scenario if you send the entire mantel clock or the Grandfather movement (mechanism): B2 or B3 or B-13-rotor rebuilding $150.00 Labor $50.00 Shipping via UPS ground $50.00 Total $250.00 If you or the clock does not have its original rotor according to the back plate, which covers the back of the rotor, then I can supply the original rotor. As an example, the back plate will have something like "Mod. 59M31", or "Model M31", both mean the same thing, the original rotor was an M-31. If the rotor in your clock is NOT an M-31 and that's what you'd like then the "swap" would cost an additional $150.00 or $400.00 total. B3-rotor rebuilding $150.00 Labor $50.00 My supplying the M-31 rotor $150.00 Shipping via UPS ground $50.00 Total $400.00 The reason for the very high "swap" price is because the M-31 is now the rarest rotor in the world and I have less than 10 in inventory. All aluminum "B-13" rotors are replacement rotors. Meaning that they were manufactured after your clock was made in order to save production costs on replacements. For an extra $75.00, I can replace your aluminum cased "B-13" rotor with an older nickel cased "B-3" rotor. The "B-3" has copper plates and will generally last 2 to 4 times longer then their aluminum counter parts ($325.00 total). B-3-rotor rebuilding $150.00 Taking a "B-3" from inventory $75.00 Labor $50.00 Shipping via UPS ground $50.00 Total $325.00 If a coil is needed then add $100.00 to each of the above. This is rare.
If the movement needs rebuilding then add $500.00 to each of the above. Some early (1920's) Herschede and Revere electrics had a rotor wound spring and working pendulum. These unique pieces cost $600.00 to overhaul the movement in the mantel clock and $900.00 for the grandfather/mother clock. These came in both Grandfather/mother cases as well as mantel clocks. All would have a place on the back plate to initially wind the movement with a flat head screwdriver. Needing a overhaul is somewhat rare and depends how long the Revere has been in service. The earliest were made in the 1920's and many were sold in the 1930's to 1960's. So after 80+ years of running, the mechanism is probably on its last legs. But some just keep on going. What I'm trying to say is that the necessity of an overhaul is unknown until I test it.
However, movement rebuilding on any Grandfather or Grandmother, adds $900.00 to each of the above.
When you send the entire clock a new electric cord and plug is included, if needed, with the color choices of black, white, or brown and in the length of your choice.
If you open or remove the back door on your Herschede or Revere chiming clock, you will see an embossed number. This number is usually located at the lower right on the movement (mechanism). With this number you can look up the date of its manufacturer.
I would like payment by money order, certified check, personal check, business check, or through Pay Pal or Square, which is the only way I take credit cards. I do prefer a check over Pay Pal or Square because Pay Pal and Square take 3%. I only take credit cards if you are in the USA or Canada. The 3% is added to the total bill if you use a credit card. With Pay Pal you can pay me directly using "friends and family" where you absorb all fees and I'm paid the full amount. There would be nothing added amount to the final fill if you absorb all fees. Here you log on to Pay Pal and send me the full amount of my bill, so there is no E-voice coming from me with this method and you will be charged all Pay Pal fees on top of my final bill. With either Pay Pal or Square, I will send an invoice to your E-mail address. Here you are dealing directly with either service and not me. You do have to be a member of Pay Pal in order to issue a payment but you may use Square without any membership or additional Square fees but the 3% will be added to your total bill as with Pay Pal. With Square, I can also take the credit card information which includes the number, expiration date and the last 3 or 4 #'s of the security code from the back of the card BUT that adds 3.5% to the final bill. I'd prefer to avoid this method but it is an option. All of the added fees are exactly what either service charges me for taking your credit card.
