I just bought a Knight 95 and will restore. It has UL connected EL34 power tubes. Anyone have any experience with this rather rare amplifier?

Here is the schematics. KNIGHT KA-95 SCH Service Manual download, schematics, eeprom, repair info for electronics experts
Nothing unusual about it, except the series heaters for the triodes.

Over 525V on the first cap. Choose your parts well.

I ordered 600 volts capacitors. That is two 600 volt for first two sections and 500 volt for rest of capacitors downstream. Rectifier tube warm up time will guarantee less that the 500 volts on downstream capacitors.

I had one, I sent it to Florida in 2012, during the purge, I wasn't enamored with the looks, or the circuit boards. It had nice transformers and it was quite heavy. One of the reasons I didn't use it for a donor was the transformers didn't have covers on both sides.It was basically a Mullard 5-20 circuit.

Did you roll tubes in it and like the sound?

Except for basic tests, I didn't listen to it. I had too much stuff (and still do) to keep all of it, so I was in purge mode and didn't spend too much time with it.
I have a pair of BTH amps that have a nearly identical schematic, which are on my keepers list, and they sound better than most amps that I have heard.

Well, the amp came and is like new condition. The killer deal is due to having four Mullard EL34 xf1, two Mullard GZ34 and four Mullard 12AX7s. Power & rectifier tubes show little use with no red line at getter edge and have absolutely crystal clear glass. The tubes are worth more than what I paid for the amp.

The EF-86's are likely Amperex
