Now this you didn't see coming....

The 009 on the KGST is indeed just about perfect.  :)  We will see some further development of that circuit in the future as I have some ideas...  ;D 

 

The circlotron will come but I doubt many will be crazy enough to build it.  The PSU scares me no end and it will be the first amp to have a very specific BOM as you can't just use something at this level.

I have cascaded plate loads on small signal tubes, and preferred the sonics to single device CCS, or resistor. I was planning on trying it on my KGST, but now my new 009s are imbalanced. Grrrrrrrrrr.

Over on DIYaudio there are several threads about the 10M90S, and of particular interest was that cascading it with a DN2540 (not another 10M90S) gave best measured performance. I think that was from a Walt Jung article.

Over at Gary Pimm's website he has some measured performance graphs of various CCS.

Near the bottom are single device graphs.

Locally he is a tech at Tektronics HQ (or was, haven't talked with him in years). He got me into CCS tube loads. Some of his later designs are more sophisicated.

No need to buy $200 worth of parts for free shipping or $40 for under $200 to us here in Aus.

RSComponents doesn't stock MPSW sand only MPSA.

 

http://au.mouser.com/Search/Refine.aspx?Keyword=mpsw42Has 3387 and 4132 in stock.
