Sound impressions since I finished my quickie.

Thanks for lending me a brain and doing all of the math Paul. I really like the quickie and all of the tweaks have helped greatly reduce the microphonics. I'm wondering about changing caps and or adding the pjccs.

I will try to get the input sensitivity of the amps but just to give you an idea, they autosense a signal and turn on. They even turn on when I tap the tubes or switches.

Will the pjccs' gain make this worse or will it just improve the bass and be about the same noise wise?

If the microphonics are that bad then you should definitely pick up some different tubes.

I really want to make this work with this amp. The microphonics are somewhat tamed so Im still up in the air as to what the PJCCS will do. I will eventually try it when I get the time. I have one more set of Sylvania tubes to roll. I might try some Mullards or Telefunkens but tube dealers are on to us and have started gouging. $30 for a pair of the aforementioned DL92s is a little ridiculous.

I agree!

You might re-wire for the 1S4 if you know what you're doing. Don't tell anyone though, or the price will shoot upfor them too!

..... but tube dealers are on to us and have started gouging....

Indeed it's been interesting to watch the price of these steadily rise since the Quickie was introduced!  Recently contacted one of the bigger UK suppliers of NOS tubes and the opening price for 10 Brimar DL92's started at £5.50 ($8.40ish) each plus taxes last email we were down to £2.50 ($3.80ish).  Now I wonder what sort of discount I'd get for 100?  I've been getting some spares from the US at $3, but wanted to try some British ones - Don't know what the life expectancy of the 3S4/DL92 is but based on 2500hrs I've got enough for a few years, had 6 in my spares box for ages and never had anything to plug them into, until now!

Update on the sound.

I replaced the batteries, added shielded 14 awg Volex power cords to my amps and changed the source interconnects to VH Audio Pulsars. These tweaks have greatly improved the bass and overall sound of my stereo. I think the shielded power cord cut down on some of the hum and hash in the sound and, in combination with the interconnects, I'm hearing a blacker background and more details.
There is a little brightness now but I think that will go away as the power cords break in.
 
I might order another quickie to test the PJCCS and swap them in and out of the system. I'll also post pictures.
