Wien Bridge Modification of an Electronics Circuit

€30-250 EUR

Completed
Posted over 5 years ago

€30-250 EUR

Paid on delivery
For the electronics circuit of TD125 (see page 18 of the attached TD125 service manual), a modification is described in the Thorens Technical Bullet #4 (see attached file) to convert the speed control from 16/33/45 rpm to 33/45/78 rpm. For the TD 125 MK II (circuit see page 19 of the TD 125 service manual) a comparable modification is missing. The outcome of the project shall offer instructions on how to modify the circuit of the TD 125 MK II, comparable to the instructions given in the Technical Bulletin #4. A completely new electronics board design is not targeted, as a good fit to the attached mechanical components on the present boards must remain guaranteed.

I understand how the Gramophone (without electricity) and Turntables (using electricity) works. I need at least 1 day to learn more details about the TD125 especially in the motor speed controller circuit section, then I have difficulty translating it into English. So it's the longest possibility to complete this, I need 30 days.
