I'm pretty partial to the knobs from Kilo over at Digikey. I like their soft-touch series, as well as some of their other ones.

I still think the spiffiest knob are those ones Peter Daniel pulled in from India. I think they were Classe styled knobs. I picked up a pair, and have been saving them for very special projects.

I do love illuminated knobs, too, though.

I am on call this week so I haven't had a chance to check the wiring. I am pretty sure that the speakers are wired separately as they should have been. I did tie the grounds together for the input and the potentiometer. I'll have a look around at it later today.

Looking good, Rich! And you have plenty room left for cigars.

Isn't it silly that such a tiny IC can give such great sound?

Nice neat wiring job. See how hard it is to drill in a straight line? Drives you crazy, yeah? For my chassis I made a drilling template, printed it on adhesive paper and stuck it in place. Still hard to keep the drill bit from wandering. Grrrr...

You've done a great job there. Very classy. Should be just the ticket with your Omega speakers. Let us know how it sounds.

Thanks, Michael!

It is a pain getting everything drilled square. My major unforced error concerns the volume knob. Originally, the power switch was to be on the right. i drilled the hole, and when the pots came, I tested them in that hole. However, I set the knob too close to the wood and gouged it a little when I turned it. So.... that became the knob hole, at the expense of longer internal wiring. Oh well...

My real fear was that the veneer was going to splinter while drilling the last hole

Here's my attempt at modding the T-Amp. Its a mesh box screen that I found at work and I attched it to a nice wood base. Sorta looks like a tube setup??

Anyway, didn't do much, no real mods per se, other than RCA plugs and Biding posts. I run it with an old Laptop Power Supply - 12 Volts and 1.8 Amp (Amps are key here!) I will continue modding this later (upgraded Caps, Resistors, etc).

Currenently undergoing a serious Burn In...8 hours and counting...

Here's the backside...

Here's the amp again next to my Other Project - a 45 wpc tube amp I aquired from a friend that I'm still fartin' with...The T-Amp was a good repreive - I don't think I can get myself killed with the 12v T-Amp, compared to the 450+ volts on the DIY Tube Amp...

Burn-In Music is Fourplay - great Burn-In CD...real dynamic, and lotsa percussion...

john65b · 11th August 2005, 04:07 AM

Sure they will, but at 12AH apeice, a bit overkill.

One will do fine. try it out.
