Thank you very much for the quick reply.  I was only able to get to 12.5 with both channels about the same.  If I go to 13.5 on one channel, the other channel only goes to about 11.5-12v.  Increasing one channel decreases the other, so that to get both about the same, I had to settle for 12.5.  Will this do?

Hi!
I have a slight problem. I hear "buzz" from the amp when I turn the volume knob just over 11 o'lock. This happens as well when I unplug the interconnect cable, so that can't cause this.
The tube is an Electro Harmonix one.
The wierd thing is, when I touch the metal jack plug of my headphone, the buzz stops. It also stops when I squeze one of the two metal poles in the front. (the ones that hold the "case" together) It sounds like a grounding problem to me. I am not really an expert on electronics, so please tell me what to do! Thanks
 
Update: Just out of curiosity, I plugged a noname microphone to the 3,5 jack in, and the buzz is gone. Obviously, I can't listen to music like this, but it might help to determine the problem.

Are these worth bidding for?

They don't seem new to me and the pins look bent...
Look for some RCA 12AU7 CONN clear tops like these: http://cgi.ebay.com/RCA-12AU7A-CLEAR-TOP-PAIR-ECC82-CONN-TEST-NOS-/330601519011?pt=Vintage_Electronics_R2&hash=item4cf962d7a3

Need to replace the AC/DC adapter to my Indeed 6922EH tube amp.
 
Model # SDK-0609
specs
Input 100-240VAC, 50-60Hz 1.8A
Output DC 24V -2A MAX
 
Any idea on who would stock this (U.S.A.) or
what other products might use this AC/DC adapter? (to narrow the search)

garage1217 sells a nice p.s. for the indeed/bravo/sunrise project.

jeremy also has a nice upgrade kit for the indeed/bravo as well as the much superior project sunrise either in kit or assembled form.

I was looking to buy one of these for fun the other day, so if it's possible can someone comment on how the bravo v2 tube amp will measure up against these:

http://cgi.ebay.com.sg/ws/eBayISAPI.dll?ViewItem&item=260795094655&ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

or these?

I have no knowledge in circuitry and the likes so they all pretty much look the same to me...

Has anyone seen this one? It looks a bit more appealing as it's enclosed and to be honest isn't a bad looking amp minus the fact that I'm not sure how you change the tube.

Did anybody already test this one: http://www.ebay.de/itm/6N11-Amplifier-Pro-Hi-Fi-Class-A-Tube-Headphone-AMP-Earpiece-Audio-Red-Demon-NIB-/320775316425?pt=LH_DefaultDomain_2&hash=item4aafb2e3c9#ht_4870wt_1398
 
It's labeled XY Hi-Fi 1.0 but I cannot find any infos in the web. I like the fact that all inputs are on the back while headphone jacks and power switch are on the front.

And another one sold as DIY kit:
http://nixiekits.eu/MiniHeadphoneAmp.htm
 
There are some measurements shown, that compare the Mr. Nixie to the Indeed.

 

[djmattm]

Wow three times more expensive than a normal Indeed / Bravo, and the differences measured are the same as the indeed / bravo modded with decent caps

In the same boat as some of you people. Looking at one of these cheap amps as a first amp but on the fence about quality as I have been reading of several of them passing away rather quickly. How have they faired for you folks?
