Re: New Members - please post your introductions here

Hello, glad to be here. I've been mending audio equipment for 50 years and now I've retired I like to keep the old hifi going. I would recommend to those newcomers to electronics to play around with some cheap components (transistors, resistors and capacitors) and a battery, just to develop soldering and measuring skills. There are plenty of simple circuit designs online to try.

A bit late but there are a few recommended replacements for the 2SB649A and 2SD669A
Fairchild KSA1220 and KSC2690
2SA1381/2SC3503 or KSA1381/KSC3503
also
2SB649-2SA1249, 2SD669-2SC3117
The MJE243/253 pair are popular drivers as well.
These drivers are operating at high voltage driving three paralleled o/p transistors, which is asking a bit much of them.

Now back to the capacitor issue. I have a C320 with DC offset drifting gradually +ve...
