I keep extracting caps. It looks like every single cap except tube ceramics will be replaced as they all exhibit x4 to x8 upward drift. This is promissing to become the largest recapping job so far for me.
Some caps are under the output transformer, so I had to extract it; no small effort.
But it will afford me the chance to also replace the filter electrolytic, plus some real long slim axial one, plus some paper ones.
There are some caps I had to parallel: 0.068uF became the 0.022+0.047, or 0.15uF = 0.1+0.047.
Most caps are soldered in such a way that they come out easy. But a couple had the leads looped.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

I'd try replacing the bulb first and if that doesn't do it, then change the 35Z5 and see if the problem goes away.NostalgiaRadioTime — 12:28 AM |
