Vintage Tube Amp

This is a fully functional GE 8950 Power Tube. Zero hours on this tube. That is when you get the actual goods straight from the factory. 30 minutes from the USA border.

7199 tested very close to new. Selenium diode has been replaced with a new production 600V volt rated bridge diode (Digikey). This amplifier uses the 7199 tubes and can use 7189 or EL84 6BQ5 output tubes.

This item is a bit of a “Mystery Box “. It was built by my father in the 60′s, who was a senior electrical engineer withBell Labs and recently passed away. I do believe it is still working, but would need to be properly tested to be certain.

These are very hard to find.

ONE AMPLIFIER = ONE PIECE (NO PAIR = ONLY ONE).

Vf 6.3 Volts / If 0.3 Ampere / Indirect / Parallel / series AC/DC.

The serial number of the A333A is 2,002. I also include an original data sheet for the A333A. As the pictures show, the amplifier is in pristine condition. All the paint is perfect and so is the lettering.

For sale is a McIntosh MC275 power amplifier that uses 6550, 12AU7, 12AX7, 12AZ7, and 12BH7A tubes. Only essential parts were changed to make sure the amplifier is working as it should. Aside from that, to my knowledge, it has many original capacitors and parts.

McIntosh MC240 power amplifier in beautiful condition. This is the earliest version of this amplifier released in 1960. The amplifier has been completely restored with new power supply, capacitors, and resistors by Fuchs Audio in New Jersey. The amp comes with 4 NOS GE 6L6GT power tubes, 2 NOS RCA 12BT7 tubes, and JJ 12AX7 tubes. The amp is warm sounding with incredibly deep bass and clarity, even by modern standards.
