Pr Altec 340A Vintage Tube Amplifiers, 1950s, Clean, Serviced, Close SN. S/N: 461 & 466. Both amps have the same Peerless transformers. Parts number on the Peerless decals: Power 6142, output 16345. Very close serial numbers clean 1950s matched pair. Amps are the same circuit – schematics are paper labels on the bottom pan. No modifications to circuit design. At some point, most likely the 60s or 70s three of the same front end capacitors in each amp were changed to vintage Cornel Dublier and Sprauge. There a few very minor chips along the bottom edges of the amps. Chassis and transformers are rust free and the paint has the original glisten. The camera picked up all kinds of reflections in the paints during the snapshots. It is not unusual to see some potting compound leak from the transformers. In this case there are stains under the output transformers of each amp. In my experience this is not a sign of any trouble. Raytheon 6550 output tubes have been tested and matched on an Amplitrex AT1000. I have experienced Raytheon 6550 tubes in government contractor’s inventory. Raytheon made a very high quality product. The AT100 does a very thorough job of testing each tube twice and carefully testing for gas and increased current draw during each tube tested. The 12AY7 and 12AU7 front end tubes are quality vintage 1960s tubes, and measure almost high. What makes these amps so unusual and have such great sound is the 0A2 regulator tube on the 6550 screen voltage. Regulation is an added expense in manufacture cost but the sound quality makes it all worthwhile. This is a solid pair of classic low production amps that sound very clean, much cleaner sound than the competition’s 6550 amplifiers. The combination of clean detailed sound and the characteristic tube amp sound quality sounds great even today. New owner should be aware power supply capacitors this old will need replacement at some time. Please have the services of an experienced tube technician for future parts upgrade. IMPORTANT – Be sure to read the Terms and Conditions of Sale. Hardware Packing – Domestic and Outside US: Item will be wrapped with bubble wrap in two directions and double boxed.

This mono tube amp would be a great project for anyone who knows how to work on tube amps or wants something to learn on. Great if you have one already and need another for stereo! Altec Lansing is known in the studio and in the hi-fi world for their quality craftsmanship and stellar audio equipment. Serial number looks like 2404 but it’s hard to read on the chassis. The unit powers up and the visible tubes begin to glow except for the 6CG7. I haven’t tested it any further. Please see photos for the specific physical condition of the unit. All of the lights on the front panel light up when switching to their respective source. I wish I could fix it up myself but I don’t have the wherewithal.
