I got the TS520S it works on Top Band but is restricted to 10 watts. If you
try to turn up the juice more than that,
it might burn the ceramic base, wire wound choke,
that sits in between the 2 B6146 valves
(well it did on mine)

Strange that... I bought a brand new one in New Zealand in 1977 and it
gave 100W output on 160m from the start. Maybe the UK version had the
10W limit factory fitted, I dont know.

I'm surprised you had trouble with the RF choke as I would have
thought the components would have been the same for both power levels,
the power reduction being made by reducing voltages on the PA.
