Starting on the HP200CD oscilaltor
#29

Yes the 6au5 and 6av5 are for TV horz driver. Also there is a bit of excess grid current in the V3 6SH7 amp tube as the HP test suggests. Not much but some. The voltage betwee cathodes of the outpht tubes should be the same or less than 1V and should not change when the multiplier switched from x10 to x100, but it does. When the 6SH7s are swapped then the voltage exceeds 1V though very little. Works fine but this sch is very sensitive.

And the last small nuisance, the tuning cap shorts when fully inside the stator, will have to look for it. Later.

IF can wire size and Rubber mounts?
Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
