I just got a couple of 40 years old Dynaco mark3 tube amps they are pretty smashed up, so i am thinking on restoring them, but the trafos dosent work anymore, so here comes the question anyone how knows were I can get some, I can use instead?
I have also heard that the Dynaco mark 3 is a very good amps, even today! Is that right or is it totally inaudible???and not worth saving?

Magnequest do reproduction ones from the original blueprints. But they're not cheap and shipping to Europe won't be either.

Model MQ 431 CL
Perhaps someone in Europe could make a replica, or you could get some second hand off ebay. They come up regularly.

Hi,
Historically and technically....,yes.
As far as NOS goes you may be able to unearth some NOS 6550s but hardly a decent KT88 GEC.
The Dynasours will be happy with either current production KT88 or 6550A.
There are more differences between the remaining manufacturers than between the type of tubes nowadays.

Hi,
If it's just the output tubes you mean then this is intersting to read:
COMPARATIVE LISTENING TEST

My first tube amp is working !!!
My Dynacos is now working!!
I have just yoused the night on rewindding the output trafos with copper core, and replaced the gz-34 tubes with dioedes
And it works and sounds fine
But is it healthy for the amps that I youse diodes insteads of the Gz-34's
Can a output tube be to old? the ones im using is more than 20 years!

Hi,
Glad to see they're working again.
Most likely the B+ is now somewhat higher than before due to the lower voltage drop of the diodes,you may need to find out what it should be according to the Dyanaco circuit diagram and up the resistor value in the PSU.
It wouldn't hurt to have them checked and replaced if necessary.
Circuit diagram:
UNCLE NED'S.
