UK: Where to buy laminations/bobbins
« on: June 25, 2019, 02:14:45 PM »
Suppose I want to make myself a small number of audio transformers. Where would I go to buy small quantities of laminations and bobbins?  Google doesn't have a clue.

Cheers

Hi Ian!

Edcor have laminations and bobbins, you can order direct from them but shipping is expensive!!!

Don-Audio has Edcor parts, bobbins and laminations!

I'm interested to know a source too for diy quantities, anywhere.

Edcor seems good but only seems to sell m6 steel laminations.

A good source of Nickel alloys lams for input transformer would be cool.

I only found a guy on ebay from korea selling nickel lams and bobbins kits but not cheap!

Very interested in old technology, i mostly learn from the info you guys share on here, so thanks!

Maybe the best way for small scale is to find a stock of suitable cores from used/surplus transformer sellers on ebay , then strip the lams and core back  and start fresh . The low profile four bobbin UI type transformers  can sometimes be found in lots , was it the 6va core you were looking at ?

https://www.ebay.co.uk/itm/Magnetek-Transformer-FP12-475/173126118068?hash=item284f1eeab4:g:b6wAAOSw3q5abfL3


Seems to be a few manufacturers used the 'Flathead' or 'FP' style including
Triad, Magnetek ,Tamura .

I checked Farnell but all I could find were ferrite cores. I know RS used to do a transformer kit years ago but that too seems to have disappeared.

Asco components, Bordesley Green, Birmingham. They have a web site that doesn't seem to be updated much, but i was there in april so it's still going.

Hi Ian, might be worth dropping Colin at AML a line or Steve at Carnhill.
See if Sowter can supply also?

..agree with mikeyB, just ask your regular transformer mfgr. They usually have surprisingly little intention of hiding what, how and with what they do..

That is exactly how I started but the laminations and bobbins I wanted to use were not ones they stock (I want to make a UI transformer not an EI type). However, they came through today and have purchased some lams and bobbins for me.

Hi Ian ,
How did the price per transformer core and bobbin work out in small volume ?

Enough lams and bobbins for 15 transformers was about £100.
