Here is a pic of the pheonix* amp my buddy Chris made from a donor console hifi amp... a Frugal-phile(tm) special (under $25 USD invested)
Stereo -- 2 tubes & 1 is a rectifier -- gotta love it. Sounds good too.
ELL80 (2 EL95s in one bottle) straped in triode for about 1.5 W. Rectifier is a hybrid bridge with an EZ81

here is my humble mini tubes headphone amp.
the amp is a ear max archetype amp,I have do some modify and use quality parts building it using P2P.

What about those metal(?)rings around the tubes?Are those for aesthetics to disguise the valve bases?Did you just glue them on?
I don't know about costs over there but all that chassis must have taken a big bite out of your amp budget but I guess worth it in the end.

Yes,those metal rings around the tubes are for aesthetics.
Rings are not pasted they is simple lay on a surface.

Nice work Digi01, that tube-headphone amp. Did you use 6GM8 (ECC86) tubes?
I made 2 of them, and i like the sound.
I used the schematic from the site www.circuitsonline.nl look in "schematics". There are schematics of the amp, and from the PSU.

Hi,
Hi Wim,
Glad you like it but it can easily be improved by changing some components.
If you like start a thread here and I'd be happy to advise. I'm sure others will chip in as well.
Cheers, 😉

845,
You obviously aren't working for a boss that says cut costs and minimize the use of expensive transformers! 😀
Nice job. I hope you added a toggle switch to turn off the local gravity when it is time to move this anchor. I built an 805 stereo amp that weighs 130 lbs. and contains eleven transformers. I need help to move it Fortunately I don't have to move it much. It is a keeper!

Actually no the 805 is a standard SE output xfmer setup. I have separate filament and plate transformers, p.s. chokes, etc. that raise the iron count. There is even a keep alive low voltage 9 VDC supply with small power xfmer to activate the SS zero crossing power relays from the hum-free low voltage DC switching in the power and standby switches that share the shielded compartment with the low level audio controls. The user protection tube cage is also wired in series with this LV control at the chassis ground return end for additional safety. No cage, no go.
I do have a design under perpetual construction (too many projects) using 8 triodes (four 6080's) all in P-SET that is parafeed.
845, What beautiful chassis' you have there. If you don't mind me asking, did the chrome plate job cost a considerable sum? It's something I've always admired, akin to the Radio Craftsmen units, but never looked into the process for fear of cost and availability.
Nice job!
Nice job!

My Thailand 6BM8 club's
I builit 6BM8 paralell single ended by 2 triode in srpp preamp and 2 pentrode in paralell poweramp.It's sound very wideband and smell (sound in Thailand) so much natural same 300B.It's watt about 7 Watts RMS.

Here, my new Foreplay preamp, just completed the front panel. Still working on the inside. See my complete story for details:
