Thanks for the offer sir. Will consider and let u know.
While i was doing some reading i came across a concern...
"The new 6H30 tube from Electro-Harmonix.
Please note that this tube can not be used in place of 6DJ8 or 6922 tubes in other pre-amps; it can only be used in equipment that is designed for it.
The 6H30 tube type is generally not compatible with 6922 and ECC88 tube types."
is this correct?
jon_p wrote:Tony,
The kt120 came as stock tubes on the amp.
As for the 6h30...are there other brands aside from sovtek?
you mentioned that you hoard tubes? All from internet purchase?

I would try plugging in a 6CG7/6FQ7 tube into the socket. Draws less heater current than a 6H30, has about the same gain and sounds MUCH better.

"I would try plugging in a 6CG7/6FQ7 tube into the socket."
This is a very strange idea. These tubes are not even close to 6H30 and their only similarity is their pin-out.

It's a good thing that I like them better than the stock tubes they replaced, thought both sets were 6550s. In my early days of audio, an older hand told me, 'pag nagbili ka ng mas mahal na kable, basta isipin mo lang na mas maganda siyang tumunog kaysa dun sa luma mo pag uwi mo'. While I do not exactly practice that, it seems to have some realistic effect.

I agree!
Have u had experience comparing kt88 vs kt120? If so, what is the diff? Power and sound?
Also read something about tube bias...according to what i read...57 milliamps for best results. Is this true? I set mine at 60 which is based on manual recommendation.
any experience or thoughts on this?

So far none. I toyed with going KT120 before I got the Gold Lion KT88s, but after chatting with some people who had the KT120s and knowing its sonic character, I decided that may not be the tube for me. How I miss the SED Winged C KT88s, which are out of production now.

Target the lowest possible setting for best sound and longer tube life. Will surf on this for my amp.
