I am sick of failing amplifiers

Heck of a story GodofW. I wish I bought a Cary Sli180 years back. They made good stuff.
Yea, my audion had a garage built enclosure. Its cheap. Unique sound. I need to give it more time.

The Blade amp with the Monolith is a work of art. 78lbs per monoblock. It does eat the mercury vapor rectifiers. But they go slow so you know it. And they cost maybe $40. No problems with the power or drivers.

845 getting worked in.
Blade on my stand. Not a good shot.
When that thing eats the rectifers, mostly are the first charging cap is too big or the resistance value of the transformer winding (mains) is too low. The recommended value (Rt) is given in the data sheet of the tube rectifier. If you do not stick to it, it will usually break very quickly.
Yes the 6SN7 is the driver.
I think the regulator is a OA3. Mine are KT88 or KT120. I need to get a quad of KT120 from Upscale to try some day.
you get more output (watt) if the circuit is adjusted. the monolith outputtransformers are wordclass.

I think he drives it at the peak of its operating potential. And my wall mount.Torus bucks.the power to about 125 volts. Is that part of the issue.

I'm quoting the "brownbook from 1959" (tube bible of studio technology Germany) tolerances higher than +- 5% are to be avoided. you are a bit out of that range. a higher heating voltage is more tolerable for the tube than too low. this leads to additional load for the circuit and its components which can be critical. try an adjustable transformer (min 500watt)and reduce the voltage to the standard value.
Exsample pay attention to the correct mains frequency.

@DasguteOhr is right! This tube needs to be run with less current: they are quite fidgety if you run then near max!! They are only used as a Voltage reference so a Zener diode could be used, eliminating the need for this tube altogether. I've heard objections because Zeners 'don't sound as good' but in my experience you can side step that problem by isolating the Zener from the circuit for which it is a reference (or fixed Voltage) with a resistor and a capacitor to ground to bypass the output of the resistor.
