NAD: VHT/Fryette Deliverance 120

[stephen sawall]

Any of you guys try different power tubes in your Deliverance ? I'm thinking of buying a set of 6550s to give a go.

Yeah I rolled all kinds of tubes in the pre and power section. EH KT88's sounded the best to me. I tried a set of Tung-Sol 6550's, and they were OK, but I had them already. I wouldn't suggest you drop the cash on a new quad of em'.
Interestingly, there is a manual available for the Deliverance and Fryette gives you a list of the recommended tubes for each position. Not surprisingly, the amp sounded best to me loaded with exactly what he specifies in the manual.
When I got the amp, it had JJ everything and sounded kinda meh to be honest. I swapped everything to the Fryette specs, and BOOM there it was.
I tried a bunch of stuff after that, but just kept coming back to the recommended config.
YMMV

I checked with Fryette first, and when I found out it was OK I ordered a pair of KT90s for my D60...if you ever wanted a HUGE sounding EL34 that is the tube...plenty of low end thump with the mids of a 34.

Real interested in what you think about the KT90 ?

Not many people use that tube.

Congrats! Always wanted to try a Deliverance or Sig X amp. Never see them around here.
