Cosmetical it is in a real nice condition even the original Tank.
Just it did not work.
I gave it to a Tech and he found out that wrong tubes were pluged.
So he changed the Tubes but the device was not working.
So my Tech replaced all the parts wich looked like older weakness.
The K10 is still Microphonic my Tech says.
I have it now over a year in repair

Want to make music with the unit so badly

Do someone here know what to do with the Microphonic problem.
thx

Edit
It is fixed now there was a resitor on the Output and this Mod made a Problem also the Reverb Tank had a Loose contact.
