The great god of surplus gives again....

I picked up this 1970's Bipolar amp for a £1 at a recent junk sale. Just in case.....the circulator shows a nice 1.5:1 when fed backward from the output, centred on 1250MHz.
Then Jim offered his 70 watt amp using the G4BAO pcb.
PCBs arrived today and as you can see, with a bit of metal surgery to remove the central pillars then some PCB surgery, a pair of them can be squeezed in. This will make a very nice DATV amp, plus keep me busy adapting and making do for several more weeks.
