Dynatron T99 Tuner

[Murphyv310]

   
Hi.
I have one of these incredible tuners. I've had it a couple of years now and have recently built a PSU for it with the space to fit in an output stage.
It works wonderfully and is about 95% original.
It does have though the dial from and earlier tuner (T69??) and there is a broken cap off one of the tuning cap trimmers on the MW band but it still works beautifully if slightly misreading on the dial, which could be the differing calibration between dials.  
Question is there a circuit diagram anywhere out there (my tuner has the B7G valves with the exception of the ECH81 and is a four gang tuner) and possibly a correct dial.

Yes, that looks like a T69B dial. I have a T69B just to look at and admire.

Hi.
Indeed they look the business
I think the later ones like the T99 & T139 are now much rarer, parts and info is really hard. I looked before for a circuit diagram with no success and I also saved a search on E-bay for Dynatron Tuner but there has not been one for two years, the T69 turns up but never the later types.

Hi Trevor,

Perhaps a stupid question but have you tried asking here: http://www.dynatronmuseum.org.uk/ContactUs.htm

I think you see the T69 a lot because it's usually partnered with an amplifier that is worth much more.

I think the T139 is also used in a "MIMCO" marine receiver.

Hi Peter.
I did try that route a couple of years ago but never got a reply. I'll give it another go though.

Hi.
Alistair D kindly sent me some onfo today but unfortunately this model isn't covered. The search goes on!

Where's Lawrence?
He usually manages to track down the most obscure information.
