well, i've discussed about this in HAS and still think ground channel is not necessary with dual pwr supply (on the other hand single pwr supply such as STEPS + virtual gnd will benefit from gnd channel circuit, and i have one with it.) this doesn't mean i disrespect the philosophy of gnd channel - i'm rather following it in my own enthusiastic way. thank you all for kind advices tho. i'll try to look up more discussions later on.

finally I got my first Dynalo cased up: (click on pics for full scale images)



I picked 2SB 647 / 2SD 667 in place of the 2SA 1015 / 2SC 1815. The power con jack is a 4pol microphone jack. What a waste of space and money, but I couldn't fit headphone jack and volume pot in one eurocard-sized enclosure :/

Here's the new CMOY I made for my son for Xmas. I was going to put a low voltage shutoff on it, but there's just not enough room in a round altoids can. It's got the TS922AIN opamp in it. It sounds pretty good for just one 9V. It's very comparable to the B-B 2132, but I think I like the 2132 better as it seems a hair bit smoother to me. Not near as much difference when running two 9V though.

finally I got one my MHs cased up: (click on pics for full scale images)

Aluminum frontpanel and acrylic top-panel are made (as usual) by Frontpanelexpress.com (though I'm still waiting for my golden FPE customer card)



Holes straight above the trimpots give direct access for tube "bias" adjustment from outside the case with a small screwdriver. The bias testpoints are socketed (break off dip strips) and airwired to small 2mm laboratory jacks on the top-panel.


This way tube rolling and bias adjustment works like a breeze, the case doesn't need to be opened or disassembled. (If you wanted it even easier you'd have to order a servant to do it for you.

)

Such a beautiful sounding and looking amp needs some decent lighting, of course. I installed 3500mcd ultrabright LEDs into the tube sockets, even at daylight the lighting is easily visible.


At darkness the tubes look like powered by serious 2kV plasma technology
