No original Marshall/Dagnall!

Even the lamination isn't 'British like' fitted into the bobbins!

DAGNEL is NOT DAGNALL :wink:

And MARSALL is NOT MARSHALL 8)

I think, that these are far east fakes.

Better keep off!

The PT is a Heyboer part. Their numbering system always starts with HTS-

Not sure on the OT. It could be a Heyboer piece as well. They never seemed to spell Dagnall right. It took 6 months to get it right on my parts...

These are on a Metro amp kit from 04'that I bought of the original owner.He said it was heyboer stuff, thought Id check.
interstingly the amp in question has a MM choke.
If it is in fact a Heyober from 04' would that make sense?

Yep, makes sense. And the kits have always used MM chokes.

If it came with my amp kit, in 2004. Then it's an early version of the Dagnall clone. Does it have self lead wires on the secondary?

They're the wires going to the impedence selector.
If they're self leads they'll be super stiff cause they're solid copper.
Just give em' a feel. I'm pretty sure they are, cause your OT looks identicle to my Metro Dagnall clone with the same misspelling.
That tranny rocks!!!! 8)

This OT still didn't have self leads.

thin brown and red are primaries to the plates. White is the primary center tap/B+

green is 16 ohms, yello is 8 ohms, black is 4 ohms...

... and you still should find a thicker brown one, that's the secondary's ground wire

Then your previous description:

was not correct!

A wire is flexibel, but a lead is stiff 8)
