6U8 (Scott used these a

6U8 and its cousin 6GH8, both of which were used extensively in tv
applications, are now being used to replace the difficult to find 7199 in
old Dynaco and other gear. Apparently the 7199 was little more than a 6GH8
with different basing and a spec for noise. There are plug in adapters
available or you can just rewire the socket. The subs yield equal or better
specs compared with the original tubes.

except that a good 6U8 is pretty hard to find, not as scarce as 7199,
but hard to find
a telefunken. Don't much like the GE'S and RCA's nor the 6GH8, except
for Sylvania's
these tubes *are used in my Scott integrateds,

I found most 6GH8s hummed in the ST-70 circuit I had which is my only
experience with them. That circuit was "phooey". I use Tele 6U8s in my
Scott, they do fine. I have about six more of them NOS.

I had a Dyna ST-70 that I dropped a new board into that used 6GH8s. I
never found one I liked. Amperex and all the other big names, bith US
and Euro, didn't work out very well.
