KT150s in Audio Research Ref 110.


Is anyone using KT150s in the Ref 110 and what is your opinion please?  ARC told me that they weren't recommended but I've read differently.  I'm currently using KT120s.

Exactly what I needed to see. Thank you jea48.  The Ref110 sounds awesome with the KT120 but I have 4 KT150 and was thinking about buying 4 more if the amp could handle the KT150s.

KT150s in Audio Research Ref 110.
The Ref110 was originally made by AR for 6550’s
I had an amp that I tried 6550’s, KT90’s KT120’s and KT150 in, it suited all.
But I found it sounded the very best using the Green Label plain white box mil spec GE 6550’s, this tube sounds way out in front of all the others for sound quality, btw the glass envelope was twice the thickness, you could tell when you ficked it with your finger nail, there was just a dead thud, instead of a ping!
Just like these > https://www.ebay.co.uk/itm/202717315969

Do you want the best? they will sound better than anything else, been there done that, as I mentioned.

For several years I had auto-bias integrated and power amps and I went through all the power tubes (and several small pre tubes). I ran El34, kt77, kt120, kt150, Kt88, 6550. I kept coming back to the El34s and the 6550s. At the time I had a pair of Spendor sp2/3s that the Sovtek 6550s sounded wonderful with. The Sovteks were new production and reasonably priced.
