What to build next in the ODS-100 department ???

[lovetone]

is that 76V -Ve or -VE?

[lovetone]

Sorry is the last 76V negative or positive?

[67plexi]

That's positive. I found some problems. I have a short I have to find.

[lovetone]

O.K.

Check the de coupling capacitors from the phase inverter, these are connected to pins 1 and 6 on the phase inverter tube 0.05uf

Check the one that feed the output tubes where you have 76 volts this is a good place to start.

Its late in the U.K so I’ll check in tomorrow to see how your getting on.

Geoff thank you for the insight

I can't see it but I'm getting B+ 500v on pin 5 power tube socket
3 & 4 some how it's connected pin 5 & 6 new one for me.
I think the Belton tube or valve sockets are the oat's that have been run through the horse. Made by the tai-wankers.

I found it look at the 8 pin socket, pin 4&5 are connected
To think I test every part and missed this.

Nice find Steve
pic is a little out of focus ...is it a solder blob or a bad socket?

Out of focus? I didn't notice. You've been drinking, haven't you? I thought we were looking at the reddish crescent about a foot below the vise jaws. That's it, right?

Drinkin...who me...nah I catn tpye wen imn dirkn.

Well done! I knew there was a fault in the output stage. I’d keep the 504 Volts on the plates and adjust the dropper string you can get it all from the first resistor, it will make a nice amp.
