The test card need a little re centering but it gives some idea of the quality.

Many of these VT161s and the BRW BR217s required very little servicing throughout a long service life. Maybe a PCC84 in the tuner, a PL81 LOP valve or more likely a PY32 HT rectifier. That was about it.

An almost identical circuit to the later Ferguson printed circuit 500 series 110 degree models. I suspect that these high quality hand wired 'specials' were produced at the Hainault factory.

Nice to see a few have survived. John.
