I liked the TPA3116 chip so tried a TPA3255 with 36v 5A power supply. Sounds pretty much the same, not sure what I expected though.

A Dynaco Stereo 80 built in 1970, recapped with new transistors. Soooo close to tube sound.

I got curious and bought a TPA3116D2 digital amplifier board for 10$ and a ac/dc 24v 4a power supply for 18$. Put it together on a board and surprised how good it sounded so stuffed it in an old cigar box.

Been awhile but here newest thing. Magnavox 6v6 push pull from a 1962(?) console. Recapped with some orange drops, added on/off switch and new grounded power cord. Sounds great

Bought a lot of ST-12 style tubes for few dollars, found two 6Z4’s that work in an amp I got so it’s a good deal.

Spicy tube…

Here’s a dangerous little bastard. I got this in 2007 when I started playing with tube stuff, almost free. Was happy until I read why they’re called Widowmakers. I hooked it up gently to test it then put it back in its original plastic bag and box. Mint condition.

Sylvania VT-107A(6V6GT). >2% matched, sound good.

Got to love old packaging, like something from The Jetsons.

Replaced the .05uf cap with a .22uf. Hooked up a Bose 2.2 IV series speaker. It’s sounds much better.

Got a pair of Sylvania 6K6GT black plate chrome domes for 6$.

It somewhat works, not impressed at all with it, this is full volume so something’s wrong.

I got everything together to make one channel of that 6EM7 amp. Only transformer I got unused is 385VDC, so filaments will have separate 6.3, and I’ll use the Variac to make 250VDC. If not tomorrow then this weekend I’ll solder it up and see what happens, note the 78yo cap 😂

Pair of matching number Philco 6GL7 tubes. They’re like a pre and power tube in one. I’m thinking of doing something with these next.

Cheap little Bluetooth tube preamp, tried 6k4 tubes but the 12vdc power just isn’t enough. Changed to 5654’s, better. Running into a 6T9 2.5w amp and Bose 2.2’s I bought in 1992.

My final pair of 6SN7’s, also my favorites. Coin base, black plate, chrome top Sylvania’s. 🤤

@mattdavala.bsky.social I got this little McMartin LT80A because I wanted to build a 12ax7 preamp with remote input select and volume/power control. But it seems all there, if it powers up and works I might have to rethink this.

Pair of Psvane 6SN7’s.

I thought the filament would still glow but guess not.

Another pair of Sylvania 6SN7’s, black plate chrome tops. These have red letters, other pair is green letter.

Well….shit.

Sylvania 6SN7 black plate, chrome domes.

Couple 6J1’s with a KT88 in background.

Pair of 6H8C’s, the Russian version of the 6SN7.

Pair of RCA 6SN7 tubes. I got 8 of these dirt cheap.

My 300B collecting dust. Got it all together but no 3.5K OT so I used a 5K to make sure it worked, removed OT’s and it sits. Maybe this year 🤷

Pair of RCA 6K6GT tubes. This is the last of the power tube pairs I got.

Pair of Groove Tubes 6V6GTR’s. I believe these were manufactured by Electro-Harmonix.

Pair of Nuclear brand 6V6GT’s, black plate, sound really good, probably manufactured by RCA.

Pair of Sylvania 807’s with 5 pin to 8 pin adapters. A higher voltage variant of the 6L6GC.

Pair of Psvane EL34’s .

Pair of Electro-Harmonix EL34’s.

Pair of Svetlana EL34 / 6CA7’s.

Pair of Valve Art brand KT88 tubes manufactured by Shuguang.

Pair of Sovtek 5881’s with coin base. Another variant of the 6L6 series.

Pair of Shuguang 6P3P. Chinese variant of the 6L6G series.

Pair of Sylvania 6L6GB tubes. Black plate chrome tops.

Before I built that green 807 I built one on a board, that later became the base for that Frankenstein amp. Cannibalism is a fun necessity. The cheap Fonon 807’s glowed this beautiful blue fluorescence. Then one made a lot of sparkles and died.

The warm glow of tubes on a cold night.

The mighty KT88 tubes 👌

A pair of 6W4GT tubes turning AC to DC.

The insides of a McMartin LT-80A Amplifier. I love the old school wiring.

The littlest tube amp, 10$ on eBay. Put some good Voskhod Rocket 6J1P-EV tubes in. Wish they didn’t put the blue LEDs in, amber would be better if they had to put something there.

Picked up a couple NOS 6K6GT tubes for 2$, replaced the 6V6GT’s in my little Frankenstein amp , sounds good but definitely lost some volume.

The 6P1 amp from that Motorola carcass. The “pudding amp”, named for the pudding cups covering output transformers. No high class stuff here 😂

Brought out the 807 for Christmas.

One of those 150$ DIY Chinese tube amps on eBay. 3 years and still works fine. Svetlana 6P1P and 6N2 tubes.

Built this one just for Sylvania tubes I’ve collected. 6L6GB , 6SN7GTB and a 6GY5GA. All NOS black plate chrome domes.

Literally built from spare parts a few months ago. Some 6V6GT-R’s, a couple 6N2’s and a VT-84 rectifier. Nice sounding for what it is.
