Biased down to 52mv(lowest it would go) with some Genalex Gold Lions KT66 <br /> <br /> Ohhhh man what a nice sound.<br /> <br /> Going to be a nice test for Jeffry Falla. His book "Hot rod your Fender" says the stock trans will be ok with the added voltage. <br /> <br /> As for HRDs go .. sounds really good!

I have a Marshall Vintage Modern fitted with KT-66s. I don't know how to explain what I'm hearing but they sure are sweet, acknowledging the amp is designed for them. Certainly different from 6L6s.

I have a Mahalo Katy 66 with a pair of KT-66's. It is a 50 watt beast!

Kt66 are a stretch for the 6L6GC transformer, but after playing an hour or so it looks like it handles KT66s fine. <br /> <br /> The edges of the notes or more round and smoother than 6l6GC's & the amp had a more "open loose feel" <br /> <br /> As loose and big as 6l6GC are... IMO Kt66 are even more of that. I think 6l6GC are crisper and have a tighter bottom end. <br /> <br /> I like them (i.e the KT66) after warming up and not on purpose I immediately drifted into Cream's Sunshine on your Love" I laughed because<br /> <br /> Clapton used a Blues Breaker 45 with Kt66 in that era... although in no way is a HRD a Marshall Blues Breaker 45, it's of the Bassman tone stack family (hence early marshall'ish) putting KT66 and running the Drive gave me that vibe. <br /> <br /> The HRDeluxe I have as been modded by a real good tech the Drive channel is pretty good as far as HRDs go... I using KT66 even added something..
