Product Description

I’m reluctantly selling y 600w 2m amplifier after having owned it for 7 years. I recently built a solid state SSPA amplifier which I now use exclusively after finding it much more convenient.

This amp was used on many of the Camb-Hams DX’peditions and when used it’s mainly been for Meteor Scatter which drives it at 50% duty cycle (30 seconds on, 30 off).

I fitted new valves on 15th December 2011 after I thought the originals were no longer working, I then found I’d wired the input/output the wrong way round.  I have a number of spare 4CX250B valves I’ll supply with the amplifier.

It has taken me a long tie to selling this as I found this amp very good, solid and reliable. Other agree;
