Rør trafo

Hi

I am just about to start rewinding a mains transformer for a Beard M70mkII - I have decided to give it a go as A)it costs 500kr instead of a replacement trafo which is 4000kr and because the replacement is toroidal and will change the sound I would have to replace the working trafo which would mean 8000kr - I am waiting for the winding wire from Brocott in the UK (which I can recommend for service). If anyone has any experience of rewinding I would like to hear from them and if youre interested I can post how I get on. The first thing to do is to make a winding machine....

Yes, we are very interested!
Go on!
And we want pictures!
Do you understand norwegian?

Ja! Bare svar på norsk/svensk/dansk ikke finsk!

Är du från UK men bor i Norge?

Yes - Ive lived in Oslo for a number of years - brought with me old British hifi and have collected more since being here. Most of it has been rebuilt several times by me - my current projects are a pair of esl57 hf units that will go into stacked quads, the Beard amp which will power them and a French turntable with old British arm.

here is some photos of the trafo being unwound - it has two secondary windings a 270v AC (1A) and a 6.3v heater with centre tap (10.5A). Its the primary that seems to have burnt out so its a complete rewind.

Det här ska bli spännande att följa fortsättningen på!

Och förresten... Välkommen hit!

Kanske en bild på den franska platespilleren? En ERA?

Siden du legger i vei med dette, regner jeg med at du har den nødvendige experience.
Jeg fikk nylig viklet om en trafo til en rørforsterker med 2 x KT88 i hver kanal. Det ble gjort i Mexico.
Kan gi en link til "viklemannen" når jeg finner den.
Kom på kr 1150,- inkl flyfrakt.
Tror den veide ca 7.5 kg.
