Default Dial Cord Beomaster 1400

Hello All,

I am trying to restring a Beomaster 1400 which will require a degree of patience.

So as I don't get it back to front as it were, can anyone tell me whether the vanes in the variable tuning cap should be fully meshed - or fully unmeshed - when the dial pointer is at the low end of the FM band (87 MHz)?

Counter-intuitively, the dial scale has the low numbers at the right hand end.

Many thanks,

Simon

Hi Simon,
At the lower frequency the v cap will be fully meshed
Cheers

Hello,

I'm going slightly off topic here, but while going googly eyed figuring out how to restring my ancient Beomaster, I notice the set has been "got at" - quite neatly - which maybe suggests some sort of professional bodge.

There is a small square of very thin plywood separating two of the AM and FM tuning coils, and what look like thin veroboard inserts into the AM/FM detector coil.

Does anyone care to hazard a guess as to what might be going on here?

Haven't powered this up yet, as I'm not happy with the mains switch so I can't comment on functionality.

The plywood between the cans could be forcing a bad joint to make contact, don’t know about the veroboard in the cans.

I don't know that set, but I recognise that the "IFT can" is a small daughter-board in a screening can, maybe the AM detector or something

Hi Julian,

So what I thought was a veroboard insert could be part of the daughter-board? It is indeed an FM/AM detector.

Interesting.

Thanks,

Simon
