Herron VTPH-2A discontinued

Sold mine and regret it daily. Tried to buy another a few times but too late (again last night). On the hunt!

It's a keeper, what I said from the beginning and totally unoriginal, was only repeating what others had said before me. One of the many things that sold me on it, the number of guys who said they are done looking. Lots of other stuff to work on, but the phono stage is not one of them. To build something so good is quite an accomplishment, especially considering the phono stage is probably the most critically demanding component in the whole audio chain. Quite an accomplishment.

Correct @lewm. 4 x 12AX7 = 44dB, 2 x 12AX7 + 2 x 12AT7 = 42dB.

When Frank Van Alstine was installing his own circuit into the Dynaco PAS 2 & 3 pre-amps (in the 1980’s), he was using 5751 tubes in place of the stock 12AX7’s. The 5751 provides somewhat lower gain than the 12AX7, but Frank prefers it’s operational characteristics.

Roger Modjeski wasn’t a fan of the 12AX7 for phono gain usage (though he used that tube for the input/gain stage of his marvelous little RM- 10 power amp), preferring the 6DJ8. Tim de Paravicini (EAR-Yoshino) agreed with Roger, using the higher voltage version of the 6DJ8---the 7DJ8---in his pre-amps, for both phono and line stages.

That’s a bummer. Thanks inflation. I own a VPTH-2A and love it! Aside from switching out tube when they croak, I wonder how long one can expect a unit like this to last?
