Never saw this one before. It just resurfaced so I'm dragging it over here.

I own that amp. Kegger did a great job on the design and build.

Think of him every time I play my KT-88 SE.

Me too
He rewired my Allen 90's (KT88’s)
They are magnificent
Thanks Kegger

That looks interesting!

Here is the schematic Keg and I worked up for my GM70 SET amp. It drives my midrange horns with the JBL2441 compression drivers. It is extremely powerful and detailed and clean.

djnagle,
What kind of transformers / power supply did you put with that amplifier circuit?

 

[Andyman]

I still have Keg's computer with all his "musings" on it. I'm not fluent enough to comprehend what they all mean, and they are in a proprietry format that only opens in the SPICE program on the computer. I have another local here who was a good friend of Keg's interested in it, but we haven't been able to get together to pass it on.

Hopefully, we can get it in more knowing hands soon.

Sounds great.

I'm building that 6LU8 amp right now on my channel. I'm about 3/4 of the way through, I suspect it's going to sound nice!

This is a very interesting looking amplifier!! What kind of power supply did you use to get that combination of plate voltage and current?

 

[djnagle]

I started with a 750-0-750 PT and run that through two 6D22 rec tubes then onto chokes and caps. It come out at around 873 volts DC.

I don't really know if this is the right place for me to post this.
But here goes.
Kegger built 2 amps for me they are Allen organ 90s he rewired them for high-fi.
I've got the schematic if you need it but it's posted early in this forum.

Anyway I'm looking for another Allen 90 hopefully for parts or for rebuilding as the ones I have are pretty tired and the chokes are burnt.

Please let me know if they're any questions thanks
Marco
