Re: Replacing a 5000 pF capacitor with 4700 pF
Thanks for all the responses. Apologies for the poor picture quality, it is yellow, purple, red.
@David: this is indeed C13 of the RF-1U signal generator. C13 to 15 were described in a thread from last year as being important for proper oscillation of the triode section of the ECF80 valve so I thought of trying a swap. It made no difference, as you have stated.
