Akkord 'Jonny' K57 schematics? (Should read M58).
Can anyone supply me with the schematics for this set please?
It is a very similar model to that in my earlier request in thread; https://www.vintage-radio.net/forum/...ad.php?t=19100 It is so similar that I can probably get by with the schematics Howard supplied me with for the K58. However the M57 appears to use 90v HT and V1 is a DK96 whereas the K58 uses 75v HT and V1 is a DK92, so there may be other important circuit differences as well. Any assistance appreciated. |

I think this is what you need.

Thanks for that Peter, its very much appreciated.
However I've just noticed that I made a mistake in the model numbers. I've transposed the two numbers. I actually have a K57 and a M58, not as I have stated in the title and my first post in this thread. But the schematic you've provided is closer than the data I already have. Don't suppose you've also got the M58 schematic which I should have asked for in the first place? Last edited by Robert Darwent; 2nd Aug 2007 at 1:40 am. |

That's OK Peter, thanks again for the M57 pdf
I've done a bit of digging on the internet and believe the M58 that I have is virtually identical to the M57. The only difference I can see is that the M58 uses a DK96 first valve, whereas the M57 uses a DK92. Everything else appears the same. Your help was much appreciated |
