Previous RH84 amps I built sounded very good, which prompted me to build one with reasonably nice parts throughout... No electrolytics in the PS Solen and ASC caps instead, Mills and TKD resistors, Elna Cerafine for the EL84 bypass, TKD 2CP-2511 volume pot, Transcendar 10W output transformers, Edcor power transformer, Hammond choke and filament transformer... Two 6AX4 chosen for rectifier duty mainly because of vinylsavor and his interesting web pages... Still not done completely filament voltage feeding EL84 and ECC81 is slightly higher and couple other subtle revisions need to be done, other than that it's been finished...
Was it worth spending all that money? This one's a keeper, I'll only say that much...

The Power amp is a highly modified OddWatt. I have two sets of tubes:

a) TungSol 6SL7 + Raytheon 6550 [ non-electric Jazz ]
b) RCA 6SL7 + GT KT88 [ Rock ]

The Pre-Amp is a highly modified blue-velvet Preamp directly connected to the output pin of the CD player's DAC chip.

Enjoy!

What mean with non-electric Jazz and Rock?
Availability in electric diagrams?

Stereo Class A Ultralinear Power Amplifier - 6G6G + 807

First idea: what to do with an old (1942) destroyed radio?

Maybe remove all rusted components inside and build a new stereo amplifier?

Let see...

Default Simple SE

This is my Simple SE (Tubelab PCB) with Gold Lion reissue KT88's and 12AT7 driver... Edcor transformers. I had the front bezel lasered at work. I haven't wired the CFB switch yet and I don't know that I will unless I decide to sell. UL is switchable though for more juice. Approximately 6-7 watts in SET and 8-9 in UL before any serious distortion occurs. Love the sound... detailed, clean, warm... only the music gets through. Thanks to George at Tubelab for all his hard work in bringing excellent sound quality to the laymen!!

I recently caught the DIY audio bug. At 52 years old I'm finally getting back to really listening to music. Here's my first project. Its a 3W cathode follower from Transcendent Sound, a TS grounded grid and Tang Band W8-1772 based bass reflex speakers. Phono preamp coming soon.

Hmm, this may be off topic but I can't help wondering what's going on here. I have noticed that people who build George's amps generally (almost all of them) take good pictures of their amps. When I say good pictures I mean kinda artistic pics. I find this interesting and curious. And not only the pictures, chassis are also above average build quality. There must be a reason behind this but I can't quite figure it out.
