The amplifier has 2 new 3CX800A7 Eimac tubes just recently installed. The tubes have less than ten minutes transmit time on them.

The tuner and amp will be sold together. I will not separate them. The amp power supply is very heavy so this is a local deal only. I will drive a reasonable distance to avoid shipping. This is a one way deal. Units are sold without any guarantees and will not be refunded. The tubes can be easily destroyed during tune up if the proper method is not followed. $3200 for the amplifier, old tubes and the tuner.; Listing #1767554 - Submitted on 05/09/26 by Callsign KT5D, Modified on 05/10/26 - IP: syn-047-040-218-042.res.spectrum.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend

Hallicrafters HT33 Amplifier: I have for sale a Hallicrafters HT33 Amplifier. It runs a pair of Eimac 4cx300’s. The amplifier is in good overall condition, it does have a few scratches but for its age it is nice. It is grid driven so it only requires about 10 watts of drive for 600 watts of output. It is only currently working on 80 and 40 meters. I believe it has a problem in the input circuit but I am not sure where. It also includes an extra bandswitch, tank circuit and input circuit including bandswitch along with the original manual. I am located in Plain City Ohio which is about 45 minutes from the Dayton Hamvention just outside Columbus, Ohio.
I have many more pictures available, if you are interested.
This unit is for local pick up only because of weight.
