Dear Steve and all.
The PA devices in the Ropex are IRF1010N mosfets (Farnell part no. 637-397
at £3.10 each) and the driver chip, which may have gone with them, is an
SG3525. Farnell part 408-359 at £1.14 each.
I hope that helps!

I have just had a telephone call from Bob G8RW to say that his Ropex TX
has failed. He suspects that the PA devices have blown, after giving
many months of reliable service. As a result, Bob is currently QRT on
136 kHz.
Bob has tried to identify the semiconductors used, but is unable to
locate any markings or part numbers on the Ropex PA devices.
Does anyone know what devices are used in this TX; and where they may be
obtained?
Regards to all,
Steve GW4ALG
