Hi,
a quick chime in from across the pond (I think this has been discussed before...):
For Europe you can contact Barthel HF in Aachen, Germany. They work together with BPT in the US and can do the same repairs (essentially any manufacturer's RF amplifiers - they also manufacture all kinds of RF stuff): www.barthel-hf.com
They, just like BPT, also offer an upgrade to AMT amplifiers that I can only recommend (which was developed by Lowell) that will prevent the typical catastrophic failure of a dying power supply killing one or both amplifier bricks...
If needed/desired I can supply customers with a loan amplifier during repair time (which may take a couple of weeks - at least here in Europe due to parts coming from the US). I have a variety of AMTs in stock for this.
Best regards,
Bert
