Re: D-inspired amps

10thTx, I should probably start a new thread for this since it looks like I'm not supposed to discuss builds in this reference part of the forum, and I don't want to distract from your thread, so I probably will in time. I found your schematics after I finished the first draft of my cut and paste sk...

Re: D-inspired amps

I changed the D'Mars ODS to have two cathode followers. The board shown is the original Hoffman style layout board sold by Doug Hoffman (EL34 World). This is my best sounding amp build to date. VERY VERY sweet musically! Nice smooth sustain and great clear clean tones, IMO. Best I can describe this...

Re: New Build- Modded ODS Type #0124 Using Sub-Miniature Dual Triodes & Miniature Output Valves/Tubes

Hi Marcus, Good to hear from you and thanks for the feedback. I agree, it's great to have Ampmaker as a UK based source. I've been buying stuff, mainly transformers from Barry for a while. I have used his 0-190-275 PT in several builds both toroidal and lay down version. It's so compact and perfect ...

Re: New Build- Modded ODS Type #0124 Using Sub-Miniature Dual Triodes & Miniature Output Valves/Tubes

Hi Mark, Thanks for the kind words. It's been a while right? I filed the various schematics that you emailed me back in 2010 and had a look at them every now and then, and finally decided to try the Dumble ODS build with the sub-miniature twist that I picked up along the way. Yes the sound is diffic...

Re: New Build- Modded ODS Type #0124 Using Sub-Miniature Dual Triodes & Miniature Output Valves/Tubes

xtian, 10thTx, Thanks for the kind words of welcome. Sorry about the sound quality, I didn't realise it was so bad, yes the iPhone microphone I was using seems to have been clipping throughout. I don't have a modified schematic, but for the preamp and most of the other circuitry I followed very clos...

New Build- Modded ODS Type #0124 Using Sub-Miniature Dual Triodes & Miniature Output Valves/Tubes

I've been lurking around The Amp Garage for a few years since I bumped into Mark Jensen Fowler on another amp building forum somewhere and he gave me a steer in this direction. Thanks Mark. Anyway after building a few Tweed and Blackface Fenders I thought I would try something a bit more complex. In...
