Default Re: PYE FV1 line output stage efficiency

Compareing the PYE FV1 and the Bush TV22
I noticed that I got a marked maximum in H-width and brightness
by adjusting the H- drive cap C52 at the FV1.

In the Bush the maximum is not that strong marked and the cap
is nearly adjusted to its minimum. I don't like this.

I did not think about this before because the set worked.

Before I got the idea with the screen grid RC I experimented
with the H- drive. I noticed the lower the resistance of R54
the more capacitance at C52 is needed to reach the maximum.
But the result is the same.
I did not change the values in the H- drive of the FV1, it is perfect!
But I think about the Bush

Kind regards
Darius
