Schiit Saga + Tube Buffer Passive Preamplifier
Fantastic preamp with switchable tube buffer ouput through a 6SN7, and a relay switched stepped attenuator volume control you don’t usually see at this price point. I’ve upgraded this unit with aluminum polymer power supply capacitors and Mundorf Supreme output capacitors. Also improved the grounding, a common issue on Schiit items (the top lid often doesn’t connect to the chassis ground).
Comes with 5 6SN7 tubes to choose from: vintage Soviet item (my favourite), new Tung Sol GTB, vintage Sylvania GTB, vintage Sylvania GTA, new J&J GTB. The Soviet tube adds the best flavour to the mix with a smooth and detailed presentation and the broadest soundstage – but if you prefer a more neutral sound the other tubes are great, or just run it in passive mode!
I have zero complaints about the performance. The soundstage is broad and deep and running the tube buffer adds a little richness to the midrange that sounds fantastic.
Like new in the original box with remote. Only selling because I built my own preamp to replace it.

Tandberg 74B 7 inch 3 speed tube amplified reel to reel deck.
An incredible 1960s reel to reel in superb, near mint shape. Serviced with new electrolytic caps, tested and running great! The magic eye record level indicators are an amazing period touch. Has a built in 3 watt tube amplifier and stereo speakers in the case, all of which sounds great, especially with the +8db bass boost EQ. Original Mullard and Telefunken tubes inside. I've ordered a replacement takeup reel belt to fix sluggish FF/RW but in the meantime it records and plays just fine.
"First released in late 1962, the series 7 was a deluxe, four-track stereo recorder with three speeds,
built-in 3 watt per channel stereo amplifier and two 7″ speakers.
It utilised a single four-pole asynchronous capacitor motor and a precision
record/playback head along with a ferrite core erase head.
Features included twin EAM 86 magic eye record level indicators, ‘joystick’
type motion selector, separate stereo volume controls, stereo inputs for
Mic & Line, stereo cathode follower and speaker outputs.

Realistic STA-64B - Junk rescue with new outputs, new pre-drivers, and a full recap.
A classic from Rat Shack that I revived after it was utterly butchered by another quote unquote "tech". It's mighty ugly inside with enough bodges to make a farm mechanic gag, but after I got done with it it works flawlessly and exhibits the warm tube-like tone and thick caramel bass you expect from a 1970s receiver. I've also doubled the power supply capacitance to eek out a few extra watts over the modest 18 watt factory rating. Surprisingly it can drive my Magnepans at modest levels without exploding into flames so it should do quite nicely with any halfway efficient speakers.
Cosmetically 7/10 with some heat warping on the plastic vent. Functionally 9/10 with no issues. Inside it's 2/10 due to the horrors this unit has witnessed, but so long as you don't peek under the hood you'd never know this little fella has been to hell and back.

SOLD Hewlett Packard 412A DC vacuum tube volt meter.
A really cool VTVM from HP's golden age of test equipment. In very good shape aside from a few scuffs and scratches. Fully serviced, recapped and calibrated and running flawlessly. A very accurate and useful tool, I hate to let it go but I don't use it enough to justify keeping it.
