Hi Martin
i bought an old 1900 and the balance was wrong . I ordered from you the potentiometer kit, following your tutorial and now this problem is fixed :). I also bought the plastic level stuff for better looking
i still have 2 problems to fix, a humm coming recurrent and Increasing with volume. Second is switch to standby mode that happens more often when the amp is in cold start, and happening less often when it warms ( it can run hours with no problem but turns off after a couple of hours).
Note that my tape bulb is dead.
As this 1900 look fine and I want to keep it, what should I buy from you to fix all those troubles. ( I also bought from you à rectifier but not replaced it yet)
many thanks from France
Ali
