Recapped, new fly, solder reflow everywhere, b+ filter cap replaced, new pots, multiple transistors replaced.

It has cirl on top on both sides, berzerk.

Did you do the curl mod? Does it do that with other boards?

I did the feeble little swap of caps and exchange with a new one, yes.
I have another chassis with zero curl

it's this chassis

I could try it in my wacko and see if the same thing happens. I'll try that tonight.
 
Bump........


There has to be some tricks/diagnosis for fixing g07 curl?

Should I look at the width cap or in tha t area?
 
well I went and checked the B+ and it was around 109

I adjusted it to 121 and now I only have very modest curl on the upper right hand side.

Is 118 the number I'm shooting for on the g07?

118 should work fine.

120 is what is it should be.

Thanks buffet, as always.
Bob says if I adjust the hor. Freq. pot, it ought to take care of the curl, I'll report back.


Oh and the curl is in the left, not the right.
 
also make sure your sync wires are correct.

well I didn't give a huge background on this particular chassis, but....

My long term, rock solid, piece of art chassis that currently resides in my berzerk is perfect, and the wiring is original (I think) so it looks perfect with no curl.

this one is now very close, I will mess with it a bit more tonight.
It's funny how many things can be efffed up if your B+ is off (I've noticed over multiple different chassis')
thanks man
