No more big power supplies for preamps

And here's a link to my latest project, still in progress...

200WPC SET Amplifier

2300VDC B+ supply...woohoo!

.

2300VDC B+?!?! Certainly one of thos "keep one hand behind your back" situations when working with these. Impressive yet DEADLY. What kind of current are you dealing with.

And I thought 1000VDC+ for 805/845 type tubes was crazy.

"...A "half full" chassis..."

A half full power supply chassis can still mean a proper circuit. Maybe the designer didn't want the power supply in the same chassis as the main circuit and/or simply did not have enough room in a single chassis for both circuits.

Ait, you are da man! Very impressive preamp and that power amp is over the top! I will follow your progress. You are certainly very good at this. Impressive to say the least.

Response 34,

The amp is in A1 up to about 40W, then it goes into A2. Current draw in A1 is 160mA for the output, then add in up to 200mA grid current in A2 at full power.

The output transformers are custom from Monolith Magnetics in Belgium, and weigh 62lbs each, with amorphous cores and teflon insulation.

Grannyring,

Thanks. I enjoy my hobby...
