[Heathkit] SB200 HELP Please

[Larry Knapp]

Larry - Others have sent you some links for Mouser.  If I need some parts I can
not find locally, Mouser is very good and needs no minimum order.

If I were you, I'd replace the 1 watt 4.7 meg resistors with 2 watters.  Also,
I would replace R4, the 15K 1/2 watt resistor with a 1 watt unit.  These
resistors are prone to going high.  I believe them to be undervalued.  Good
luck.  I'm sure the gentleman appreciates your work on his amplifier.  That's
being a good 'Elmer'.

4.7 Meg one watts resistors? I'll be happy to pay for them. I can't purchase
them any place because it's too small of an order. Regards, Larry   kh6ity
