Kone,

Nice speakers, but what is halfway through re-coning mean?

Marshall likely did not have the concept of solid state down by then so
the power supply is probably unregulated.  No prob with valves just get
close with resistors, there are hundreds of volts of swing.  Those
transistors don't like over voltage on the rails.  Also the old
electrolytics need to be checked as they may be passing pulses instead
of smoothing.

Most of the guitar amp issues stem from the power supply or the output
section losing the ground reference.

I appreciate the offer, while space is limited those speakers fit the
category of good vintage audio, a transistor Marshall not really.  Are
you coming back to the states or considering becoming a permanent
resident of Belarus?  Interesting Svet is not into the states, most
Russians love it here and unlike most other foreign cultures integrate
with Americans. 
I love South America but find after awhile I am truly a Norte Americano
and enjoy the easy access to the marketplace.  I can't stand the insane
tarrifs down there and in most of the rest of the world on automobiles
and motorcycles.  In the US a really nice used car can be had between
2-5k and over there it's 10-12k and a falling apart shitbox is about
3k.  Hope they don't bend you over on transportation there.

Did you want to put Norms presentation on youtube or should I put up an
account and go for it?
