Millett "Starving Student" hybrid amp - Page 112

Yay for pics, my completed "SS" Hybrid...





















It sounds great and I'm happy I chose to go the boutique route. There is still some fiddling I'll be doing (output resistors & bypass caps), but it good for now. I'm running it with my iModded Mini as a DAC and Senn HD580's. Its the best setup I've had thus far, moving from running RE2's on my CMoY and MBP as the DAC.

The only thing I'm not happy with is the knob and that is partly my fault for being slightly hasty. The RK27's pot shaft is a lot longer than the knob's 'depth' so the knob kind of sticks out and there's a gap behind it. Nothing a new knob can't fix. I've gone ahead and attached a BOM of my build, though I took cues from 'OldKing' and 'jERiCOh'

I have a strange 'pitter patter' type of noise on my SS, which goes when I hold my hand over the right tube.. Is this some sort of ground issue?

And also humming which goes when I touch the input RCA jacks.

Edit - Never mind, seems to be some interference picked up from my iMac, goes when I move it away.

I really like what you've done with the heatsink. Nice casework!

I was thinking of recasing my first build into this: Newegg.com - macally T-S350SU 3.5" USB & eSATA External Enclosure - External Enclosures

Cheaper!

Looks interesting... Can't tell if it's plastic or metal. If you do get one, please post details.

Thanks,

first review on Newegg.com:
"Cons: wish there was a firewire port. Construction is what you pay for ... Lots of plastic ... WARNING BE CAREFUL Swapping drives ... you can almost snap off front of enclosure when unloading a drive. It looks better than expected I changed blue led to white"

@bmw...did you have any trouble drilling thru those heat sinks? looks pretty thick

No, I had a drill press, lots of HSS bits, and a Uni-bit to aid me and a little cutting fluid. I'd say it's about 1/4" thick in that area.

cool, looks great.

I bet a drill press is a man's best friend for case work.

troubleshooting

So I built my SS yesterday, and I made a boneheaded move and mixed up the power and ground from the power connector, so it just hiccuped and burned out the switch. Now I've got things sorted out, and the amp works. However, the right channel has some kind of feedback interference which is a quieter version of the signal, but at a different frequency. So I hear the music, and also a quieter version in a different key. Any ideas what could be wrong? Could the mosfet be burned out on that side?

Thanks.

so i found a small stockpile of tubes and might end up putting some extra amps together for the less diy inclined folks here (minus psu's)

can anyone offer suggestions for a cheap quality enclosure to use?

Nice! I'm gonna order parts for a build like that any day now.

Where can I score a pair or two of tubes for this amp right now? Every place I have called always says I just missed them. Ebay has listings for around 20 shipped which seems a bit nuts considering they were 1.10 a pop originally.
Thanks

Ditto.
Let me know if you find anywhere.

Hang in there, I'm pretty sure a bunch will show up soon - and at very reasonable prices too.

Tried Orlando Vacuum Tubes ?
