Default Re: Marconi 1400 birthday present

Excellent advice there John as always. I ran the set up yesterday and was reminded of another common problem of weak signals due to a break in the UHF isolated coax socket, confirmed by wriggling the plug. Will sort that out over the next few days now I have a week off.

Speaking of these capacitors, one thing that was immediately evident when I adapted the 960 to take a 1400 Lopt when the original red one failed was lower EHT, this with a 160pf cap.. The regulation isn't very good either. Might try experimenting with the values of the disc capacitor to get it to normal levels.
Cheers
