In terms of a PSU, you could put a "wanted" request on to this forum, either for a complete one or the transformer.

Al has suggested one circuit, but an alternative is to use the cheap little LR8 regulator chip, so you could have a 250V transformer and get out stabilised 150 at the turn of a knob. There is a detailed thread somewhere on the forum (a number of us built them), but I didn't it find at first look.

I'm not sure if much goes on on 4m these days. If I recall, we were given the 5m (or was it 6m ?) band a while ago and that band is shared by many countries (including the US) whereas I think 4m was allocated in just a few countries? For anyone interested in those sorts of frequencies, it could be that the "new" band is the place to be now?
