Avalon 747 technical schematic

Without load

Did you find the 6 V and 12 V as well as the bipolar 32 V?

Without load I get
- 6.3
-12.1
- 35/-35
And the other B+, 100 volts.

I have 35 not 32 .... Is it a problème ? Thanks

Yesterday, I check the 250V caps. Guess what ?? Two Of them are so dry, they collapse only slowly when manipulate them. Its the 47 uf and the 100 uf. I change that 47 uf, now line is on 125 V... Waiting for others caps. I order it and received it today. I will finish recap tonight .. Hope that Can help the 747 to boot on correctly...
