[RTTY] Amp question

[Al Kozakiewicz]

Any of the AL-82, AL-1200 or AL-1500.  All share the same chassis, control, and HV power supply, as well as the major RF components.

The AL-82 uses a pair of 3-500 tubes.  There are multiple sources and the tubes are relatively inexpensive at about $150 each.

The AL-1200 uses the 3CX1200A7 tube, which has the advantage of being instant on.  It's only source AFAIK is Eimac and costs $1500.

The AL-1500 uses the 3CX1500 tube.  It was used in a number of MRI machines and has multiple sources. New tubes from Eimac cost $1500; new Chinese tubes can be found for about $600.

I have an AL-1500 with a Chinese tube and it has worked well for a number of RTTY contests.

Hi all,

I'd like an opinion on which Ameritron amp (1kw at least) would be best for heavy RTTY in a contest?

Off list is fine,

Thanks
