If you can get the Gold Lion KT66s in that amp it would be nice.
I built the VTA ST-70 and WOW. Just wonderful with any tube. But the GL 66's are special.

That hasn't been my experience, in my system, but it would be nice if it were.
I stuffed my board when VTA was using Auricaps, so I did the same. I subsequently replaced some of the PRP metal film resistors with tantalums, but it didn't help.
I'll get the Auricaps out of there, and try the often recommended K40 caps before I buy any more tubes for an amp that may just not be to my liking.
I also found the VTA to be more in the modern voiced camp even with K40's etc and carbon film resistors etc. I eventually replaced it with a DIYTube board and was much happier. I guess you can't please 100% of the people 100% of the time.
That's good to know, thanks. I've considered the DIYTube Poseidon board for my Dynaco MK-III amps, but never took a hard look at their ST-70 input stage.
If there was an unlimited supply of good (i.e. non-gassy) 6P3S-Es around I'd be more likely to leave the VTA input stage in my ST-70, but Jim's out of them, and buying them from ebay at this point seems like a gamble.
Twist Samra's arm not quite to the point of falling off. ;> D His pile is a "lifetime" supply for more than 1 person.
FWIW, I favor the Triode Electronics replacement ST70 driver board populated with 2X EF86s and an ECC99. The OEM signal topology is retained, while in production and superior small signal types are employed.

The EF86 is a superb input tube for both SE and PP amps. I have a small stash of NOS Mullards put away for upcoming projects. :)

Although I generally heed your advice closely, Eli, I stuck with a friendly request, so Mikey's appendages are intact. Hopefully my "I broke one of mine" plight will appeal to his altruistic side, and he'll open up his stash to sell a few.
I do remember reading that you liked the Triode Electronics boards, but had forgotten about them. I want to install a SDS power supply board in the same ST-70, and wrote Sheldon Stokes directly. He said he'd check to see if he had any made, but then never got back to me. I'll check and see what Triode Electronics has so say.
Thanks!
