Default Pye BBFM Black Box FM Adaptors X2

I am selling these on behalf on a non member.

One is all original apart from some period service work. The original 3 capacitor smoothing can has been replaced with a DALY dual capacitor can and a 60s RS axial capacitor.

The other looks like it has had all its Hunts capacitors replaced some time ago with a mixture of RS and Mullard parts.

Both have a full compliment of valves and crystals. One Pye service sheet will also be included.

Both are gloss black to match the chinoiserie Black Box (were brown ones ever made?).

Both are in OK to fair physical condition with a few bumps, scratches and scrapes. Both have different knobs.

Collection preferred as I don't have any packaging material. FCS could be used.

£100 each.

Enquiries via PM please.

What a fascinating circuit.

Fixed frequency tuning with the LO for the three(!) pre defined channels crystal controlled, and a pulse counting discriminator.

I would consider packing these if it would help somebody out.

Hello,

I could well be interested in these as I have two ‘Black’ Black Boxes…

I’m in the Sunny Southend area so they would have to be shipped

I’m going to the RetroTech if that helps...

Anyway, PM sent.

Terry
