Farnell LT30/2 power supply knob caps
Hi all. I've got a Farnell LT30/2 dated around 1982 here which is in fairly nice condition bar a missing knob cap. Does anyone know what type of knobs these are are and where to get caps for them?
I've included photo of the unit and a close up of the knobs. Any help appreciated! |

Collet knobs, in a style common across Farnell stuff of the era.
If you take one knob off (Hold knob, wide bladed screwdriver in the slots of the brass bush, turn clockwise to release) there may be clues under the skirt. Cliffe products, maybe? David

Good idea. I will attack that idea shortly. Cliff is a possibility - I have seen similar parts before somewhere but couldn't remember where.

Sifam maybe?
I have the single supply psu, will check size and see what I have later today. Rob

Re: Farnell LT30/2 power supply knob caps
You'll need to measure the original knob but you can buy the inserts from RS https://au.rs-online.com/web/p/poten...knobs/0225811/ (or the complete knob if necessary).
The part # should be the same on the UK RS site. |

If the RS one isn't a perfect match but fits, you can always change the set of them.
Sifam were very active in collet knobs, but maybe too expensive? Worth checking. David

They might be Mentor like this https://www.rapidonline.com/Catalogu...2%5d%7d&Page=2
Measure them up and look at the appropriate caps. The other possibility is Cliff or Elma, as other have suggested it is some times easier to buy a new set that match.

Re: Farnell LT30/2 power supply knob caps
Found one. Pm your details and I will pop it in the post.
Don't worry, didn't take it off my psu, that is where i did a trial fit. Rob
