Anyone tried KT77's ?

[Road King Police]

Anyone? How'd it go? I'v got a pair of JJ's hanging around, lot of hours logged on these 34's, thinking about using them.

Unless anyone has anything new to offer, I'll go with this thread.

I'm running KT's in mine and I love 'em.

Depends on the amp and what sound you're after. I like the KT77 quite a bit for it's low end extension. But you give up some of that upper mid of the EL 34

I have NOS RFT (Siemens) EL34 and an RFT 12AX7 in the PI. Rebiased around 65% Sounds fantastic in the JMD1. Did That about a week after I got the amp.

Here's a Link. Very Honest and dependable Tube dealer:

What kind of numbers did that equate to on your voltmeter?
