Studer A67 & B67 ELECTRONIC capacitor & trimmer overhaul kit

FULL Capacitor and Electronic Service Kit for Studer A67 and B67 mk 1 & 2 
Includes PSU, Tape Transport & Control and Suppression Capacitor and mains filter overhaul kit and all audio cards including sync but not time code (very rare).
Don’t waste your time replacing just one or two capacitors on machines that are now 25 - 40 years old, replace ALL the troublesome electrolytics,  tantalums and suppression capacitors. Usually the old high voltage capacitors associated with the motors and tape drive will also be shot electrically and often even visually. Some capacitors may test ok on a low voltage modern tester, however capacitors usually need to be tested after they have operated for at least 10 hours (after being discharged and stored for many years) at working voltage and then tested under actual working voltage conditions. Modern testers cant do this. For such relatively low cost components its prudent to just replace the lot.  PLEASE NOTE:  If you have a 30"/sec machine, please tell me at time of purchase as the capstan motor takes a different capacitor to the more common standard 15"/sec machine. 

This kit contains parts for all boards and is highly recommended

• Replacement capacitors for all the electrolytics including large PSU can type caps
• Replacement for all tantalum capacitors
• All troublesome suppressor capacitors on drive control, switching and mains suppression. 8x  X2 rated suppression capacitors.
