They did indeed! They're 3R9 10W reuse jobbies though so they'll be fine for this purpose.

Winters on the way so the amp will just in time for some nice cosy dark nights.

Re: DHT Heater using VCCS - PCB or Kit (Possible Group buy)

I've got most of the parts for my OTL 300B build and have started assembly; one amp on the bench with four of Andrew's supplies hooked up and under test; http://i1298.photobucket.com/albums/ag49/2a3user/300B%20OTL%20Build%20-%20DC%20Version/DSCF0916_zps5t2xznck.jpg Even I managed to get them all wor...

Re: Transcendent SE-OTL

Paul, just to make sure, you're aware that its only 1.5W per channel; I wouldn't want you to think it's one of the more powerful Transcendent amps.

Should've mentioned the output in the original post.

If you're still interested PM me and we'll sort things out.

Transcendent SE-OTL

Any potential interest here for my Transcendent SE-OTL before it goes on ebay? http://www.audio-talk.co.uk/phpBB3/viewtopic.php?f=11&t=2533&hilit=SE+OTL I'm looking to move it on in the next few weeks, once I get my 300B OTL amp rebuilt. Since the pictures above I've added a heat shield arou...

Re: DHT Heater using VCCS - PCB or Kit (Possible Group buy)

So, I can reveal why I was building eight of Andrew's DHT supplies;

I'll add something about my build in a separate thread here once it gets properly underway.

Re: Computer Music Sans DAC

I would be surprised if that mute was fast enough to suppress clicks, but I guess it depends on how its driven by the other end. The mute circuit has been successfully used by others. The relay response time spec. is about half of the 'buffer' length for the codec switch function. Anyway, as the sa...

Re: Computer Music Sans DAC

There doesn't seem to be much interest in trying this approach to DSD playback but if you have a device that outputs DSD and a few DSD tracks it is well worth trying; the results are excellent and it will cost you very little to try it. Below is a schematic showing all that is required, in it's simp...

Re: DHT Heater using VCCS - PCB or Kit (Possible Group buy)

Thanks Andrew. You know all about the project I'll be using these in but I'll not say anything further until the main man is ready to go public. :wink: On the PCBs, it was quite tricky soldering the TO92 and the small electrolytics because the pours running up to the small pads acts as a very good h...

Re: Smallish Boxes for a Squeezebox Power Supply

Check out ebay, there are some decent enclosures from China at good prices, search for 'chassis enclosure' in 'Sound and Vision'. I guess these, shipping within UK, are too small? http://www.ebay.co.uk/itm/261686299140?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT http://www.ebay.co...

Ray You certainly know how to have a good time Ray. :) Phew, all done bar the heatsink mounted parts (mica insulators not in the box, out of stock at Farnell!). Not the easiest boards to solder...
