Default Re: 'Proper' DAB conversion for valve radios

It appears that I won't be trying it after all in this particular set.

Although the mixer tube is what is replaced, it seems that the unit is really intended for AM sets. The FM version has a shield which sits over the FM mixer and detects the oscillator frequency. The output however is then post the IF and detector stages, so audio output only. Still allows tuning normally though but pointless in this particular tuner.

The AM version remains exciting though as that does actually produce an IF output. Oh well - another set will no doubt require it at some point!
