THE POWER SUPPLY

There.
All the components together on a plank.
It is absolutely HUGE!!


And very heavy too....


I guess it needs to be like this...
You get a 25W SE triode and it weight over 60Kg.
Does this have anything to do with the fact that tube amps became unpopular?
Can't imagine....

THE BIG BROTHER

Back to the EIMAC 100TH
Need a new pre-amp since the other one ended up as power amp.

Looks better!
Fits better too!
The SERIOUS power supply.
The high voltage will be seperated from the rest.
I'll make a real "power supply".
1000V 250mA

The proto type...

Works ok but still a little 50Hz.
There are no chokes mounted yet and the C's are on the small side too...
Get that fixed this week..
