Default Re: The "Sussex" Homebrew Valve Tester.

Hi Mike, as requested by another Forum member I have added transistor lead out info with ghosted outlines for TR6,7 and 8 on my sketch at the link in my last post. While doing this I think I found an error on C8 and D6 as these are reversed against the circuit diagram. I have corrected this on my sketch but just hope this is now correct as I am banking on the circuit diagram being correct i.e. C8 +ve at VR2 and -ve at TR7 emitter.
Cheers
Les
