Ha, ha tell your wife she guessed the situation right, I will come in the night.......

How can a man with such a light name like "tea-bag" choose such a heavy solution more appropriate to diyaudio fellows with name like " War Hammer" or "Copper Woolf"

Best

I have a second article about something else which I'll try to post on my blog before the end of the year.

I have the prototype PCBs, but I'll be making a couple of minor revisions. I wouldn't worry about the gain devices vanishing between now and then.

@Tea-Bag
I'm looking forward to hearing how your amps sound with those Lowthers. Are you using open baffles or cabinets?

Hello guys,
very interesting thread so far.
I am just wondering how do high voltage curves of 2sk82 look like,
this device has stated max Vd 240V. So if we have good looking curves in
higher region this could be an SET imagination... Has someone looked to this area?

Any comments on my layout?

I am worried the Power transformers and Inductors are going to hum this close.
If you can see the signal board will mount way toward the back to keep signal path small as possible. The Heatsink and SITS will mount of the top of the unit towards the back.

Tested the signal board and inductor out. Works like a champ on two diffent Sony SITs and each channel of Signal board. Just concerned about layout before drilling in place.

Hum was a non-issue for me at roughly the same distance. I wonder if you'll get some magnetic coupling between those inductors, though. I built monoblocks. I always build monoblocks.

Maybe. In crossovers, the interaction is reduced by placing them perpendicular to each other.

Inductor Placement *PIC*
