Hi Guys,
I got things working. I had a quick listen, it is one amazing amp.
No doubt about it.
I had originally sized my cabinet for one trafo, it is a 14" Par-Metal cabinet. Due to my trafo problems mentioned earlier, I am now using 4 trafos. This eliminated the space inside the cabinet pushing one channel right up alongside shunty and very close to the trafos. Not surprisingly this channel has a pretty big hum
If I removed the board amd let it hang outside the box putting some space between board and the supply the hum reduces. It looks like either I have get a new and bigger cabinet or take the trafos out and put them in a smaller cabinet and make a 2 box system.
Can anybody suggest some inexpensive cabinets?? Or could this be solved other ways??
So close, yet so far.

I'm just looking at steen's pics ....... in hope that I can find some adequate pic for dviswa but - naah ........ steen have just two xformers , potted , and Shuntys are between them and Pumpie pcbs ......
anyway , I'm just laughing ....... look at this drek - all that but only 4 active devices per channel (two per leg ) .... !

Obviously. I am not in the same league as Steen and have no desire to compete with a master
I am using the Mercury Magnetics TA110-W from ApexJr. 2 Trafos per channel. I also noticed these trafos do produce a good bit of audible hum, the Magnetostriction vibration variety. I tried tightening the screws down to stop the vibration, not much use. Don't know what trafos Steen is using. I am not too keen of pottig the trafos myself. Surely, the trafo vibration is another thing I need to fix. Any ideas on how to dampen the trafo vibrations down?

naah ....... steen is master scavenger , even if he certainly put nice gross of greenies in his scavenging
(steen is my man !)
put these buggers in bucket of varnish or glue or paint ; let them soak for 30mins and pull them out ; leave them overnight in outdoor and pray
nothing better than separate box for noisy xformer ( or noise inducing , whatever )
mumetal will help just a little , if trouble with them is already apparent .
Usually whatever i say, yes, even if i do not use that word.
(you think there's something as "Le sauvage savant" ?)
Not in this case, means : yes, also for toroids but not just that easy.
Maybe the Brittanicos find singularité too lonesome.
Pair of scissors, pair of pliers, pair of spectacles, pair of pyjamees.
