I have reduced the value of AM variable capacitors by removing vanes in the past, but it goes against the grain. Far better get a proper one. I will have a look in my spares but I may only have the open type AM/FM type with the VHF section tacked on the end of the AM gangs.

Thank you Alan! There is one on EBay but it’s in the USA so high import duty !
I appreciate you taking a look

Cheers

How about a Vega B215 FM twin gang tuning capacitor? It is well made and has a swing between 2.2 to 16pf. I have one of these and if you're interested I'll take a photo or 2.

I found a miniature 3 gang capacitor but it only measures about eight pF on two of the gangs and about 14pF on the other. I don't remember where it came from but it has a reduction drive and is probably intended for something UHF. The only others I have are combination jobs with the AM sections included.

Hi Alan

Attached are pics of the VHF tuner earlier mentioned.

There is a reduction drive but it has some backlash. However, because of tuners construction it may be possible to minimize this.

Measuring 25L X 15W X 20H mm, the body is secured by both screw and solder tag to a printed circuit board. The shaft from the reduction drive is 3mm in diameter and, as can be seen, is currently fitted with a plastic coupling used for the drive cord. It can be removed.

The item is FOC with p&p £5.

Let me have your thoughts

Regards

Chris
