Setting the Bias on a valve amplifier...

Hi Guys


Firstly can't believe how long ago I started this thread.

Anyway thanks to Rodney my Music Reference RM-100 amplifier is now back fixed and sounding brilliant. This may be in no small part because of a set of Cyro KT88 valves that Marco sold me to replace the one that blew damaging the amp.

Marco, they sound brilliant. How can I continue using a valve hybrid integrated bottom line I can't :doh:. The effortless sound, detail, musicality, ebb flow, presence of sound I heard this afternoon was magical :)

My baby's back :gig:

Hi Neil,

Nice one, mate. I'm pleased for you. It took a long while but you got there in the end :)

Your observations are interesting - sometimes you don't appreciate what's really good until it's gone...

I doubt that I could ever not use a valve power amp. Once your ears become attuned to their intrinsically musical abilities, I doubt that any ss amp could hope to replicate them.

The Cryo-treated (matched quad) Svet KT88s are superb valves. They'll get even better once they've had some proper use.

Enjoy! :cool:

Marco.

I let the amp sit for a few months until I had some money to pay for the repair, as it turned out Rodney was kind to me, £40 all in :). A friend then brought it back to me (Rodney is based about 80 miles away).

Yes I look forward to getting a few more hours on the valves and while you had some use out of them I am sure it will all bed down. I will also have to keep an eye on the bias as well.

Your right about the power side of things. Solid state pre is a different beast to a SS power amp. I have also this afternoon been engaged in trying a few pres out as well. I was doing this remember when the valve blew so I have started again. I have the Chapter Preface back in having tried 2 Bat pre-amplifier stages....both very good, and surprisingly I favoured the pre stage of the Bat VK300SE integrated over an all valve pre. Nothing conclusive yet....just an early observation. The Chapter should be very interesting as it is a fabulous pre.

Glad you got it back Neil.Yes,valves are hard to live without once you get used to them.SS just doesn't cut it for me now.
