Drake T253Y transformer

[Bushbaby]

Hi All,
does anyone have any information relating to the above transformer? I am still considering building a clone Marshall 1930 amp at some point (I've got most of the parts to do it but not really undertaken much research into the transformers).

Best Regards

Rob

Hi Rob, if you manage to get some information I can probably sort out the winding details for you.
From memory of Marshalls they used Stalloy laminations and a fairly standard (and obtainable size) of lam, with no exotic interleaving of the pri and sec.
If it is the type with shrouds fitted be aware these are quite expensive now

Cheers, Ed

Some info here on Marshall power tfmrs Rob - http://merrenaudio.com/marshall_power_transformers they use a different type designation though. That said you should be able to pull all the specs you need off the 1930 amp schematic like HT wndg ,heater windings etc.

Thanks Andy
Ed Dinning (very much appreciated) is making the power and output transformers and we have based this on the 18watt amp ones.
I still fancy a crack a building my version of the 1930 but I am aware it will need some modification.

Best Regards
