Aye,
keeping the space between both HTs constant seems to work beautifully. Guess it’s one of those happy accidents.

Re: OK…so I’m on wi’ summat
The idea came from the fact that the 6SL7s are drawing around 1mA each and I wanted to use a series VR105 tube to knock around 100V off the HT. I wanted that tube simply because unlike the 7pin VR tubes, it looks great when lit and I only have the one. I had to think of some way to make the tube pas...

Re: OK…so I’m on wi’ summat
A little more experimentation with the power supply today. I've seen series VR tubes used to feed the input stages of commercial amps such as those from Decware and Icon Audio, so I thought I'd give one a try in my own amp: EL34SEULSimplifiedPSU.png 22K shunt resistor makes sure around 15mA is flowi...

Re: OK…so I’m on wi’ summat
I don’t think they pose any danger Simon. My hairy-arsed soldering is probably to blame for the problems with mine.

Re: OK…so I’m on wi’ summat
I’m glad I got it going again with the JJ and the Sprague caps. It’s a great little amp and the ultimate quality of the sound doesn’t seem to depend on whether or not electrolytic caps or foil in oil caps are used. Yes, of course it is slightly better in the treble, with foil in oil caps but the dif...

Nope,
Still the same as it was.

Re: PSE EL84 Amplifier
I have 4 x NOS, PL36 if you want them Paul. They are Thorn or Mazda (can't be sure until I dig them out) never been used. They have 25V heaters. Might be useful?

Re: OK…so I’m on wi’ summat
Enjoy the music, Steve, that sounds like a good plan for staying off the slippery slope. Yeah that would have been nice; in fact it was very nice indeed...that is until last Thursday afternoon. The telly was on, Melanie was watching "Impossible," I was upstairs, not having turned the amp ...

Re: OK…so I’m on wi’ summat
Enjoy the music, Steve, that sounds like a good plan for staying off the slippery slope. The combination of this amplifier, the Mac Mini and the RTZ DAC (with the higher quality op-amps) is producing the best sound I’ve had in this room…ever! I think, trying to wring anything extra out of the amp m...

Re: OK…so I’m on wi’ summat
There is nothing simple, that can’t be made more complex. I needed to take a step back and ask myself if what I wanted to do was actually necessary? I seemed to be planning to up my solder connections, up the parts count, double my chances to make a mistake. Double my chances for failure, so I thoug...

Re: OK…so I’m on wi’ summat
Was going to go fixed bias (Gawd knows why.) Got all the way to building a pair of bias supplies. Tested them, they worked faultlessly then I wondered what I was playing at and thought, sod it!
Just enjoying the music instead.

Re: OK…so I’m on wi’ summat
I tried the silver mica caps from Simon, years ago. Didn’t like them I’m afraid: to call them screechy is being kind.
