Which KT-88 tube?

[HpW]

try som KT120 instead ,if you have the heater capabilities

I will consider also this KT120 tube, but will go as soon as possible with cyro threaded Cryoset.com - Cryoset Certified Vaccum Tubes as
seen on Tung Sol KT120 Cryo Matched Quad, Cryoset Online Store

while used the Gold Lion's with grid cathode shorting after head up, and also dark sounding as compared the EH KT88 using Cary SLM-100 dual mono modified ..

Hi sleiven, I am using KT-120's [DYNACO VTA ST-120] And I don't have a good quad to use as a back up set should anything go wrong. I have been using RCA cleartop 12AU7's in the pre stage .So I just want a good robust set of KT-88's or 6550's to have on hand.And yes this amp can easily run even the KT-150 tubes as well. Thank you ,Scott
