Solo100

Hi Andrea.

There was no pops or bangs or smoke. In fact it has fired up perfectly every stage of the way which is why I'm stumped.

Nothing is hot to the touch and the tubes are stone cold.

Fuses have continuity across them so are fine.

I have (give or take a volt or two) 515V across both sides of R56/57 and 58.

So I have had another look at it today and am still getting the same voltages everywhere.

It all seems to be hovering around the 520V. On all the test points on the tubes and the B+ points too.

I checked my PT and that's giving me 120v which is fine. Then I'm getting 376v to D1-D4 on the HT.

I'm getting 62v to the bias.

3.3v on each wire to the faux CT

And 3.5v on each wire to the bridge rectifier.

I have double checked all the wiring and so far I can't see a mistake.

Does anyone have any bright ideas?
