All the following from manufacturer's data.

10 W per channel. Push-Pull ECL86's for output. Silicon diodes in PSU
voltage doubler.

Range of 6 plug-in adaptors were available to match various cartridges for
LPs. (Hence you may need to check which one is present.) The standard was
to supply two adaptors with the amp - one for mm, one for ceramic. So
probably you'll have the standard mm one.

FR 20 Hz - 20 kHz +/- 0.5dB (pre) +/- 2dB (power)
THD 0.25% 1kHz 5 Watts, 0.8% 1kHz 10 Watts
Hum+Noise -80dB below 10 Watts
Outputs for 3-5 Ohm and 12-16 Ohm loads

Valves 4 x ECL86 (power section), 3 x ECC807 (pre section)
Diodes 2 x BY114 (Silicon)

Radio 100mV 470kOhm
Tape 600mV
MM Disc (Standard) 3.8mV 68kOhm

Most other stuff should be obvious - e.g. 5-pin DIN Tape socket on front
that parallels tape sockets on back.

Slainte,

Jim

I believe that some of the Cadets were only fitted with ECL82s, so are
likely to give less power.

I had one of those 30 years ago, it was crap, get rid of it quickly, some
twerp will probably part with £250 just because it's got valves in it.

I've had it running and thought it was quite nice sounding - not at all bad
for 30 year old technology :-)

probably go for around £100
