Hi Everybody
I'm Italian and I live in London, UK.
I just received this old MP-1 I got on ebay. Before doing any upgrades or mods I wanted to just make it work.
It's a v1.38
I powered it with a variac at 113vac. The unit turns on and the display says "c xxx" with the numbers going up till 128 and then stops.
I plugged a guitar in the front input (line input jack broke off just by touching it, output A is also broken)
I am connecting outputB to a solid state power amp and a 4x12.
The tubes filaments light up. They are Groove tubes, I haven't pulled them out but i will test them on a tube tester ASAP.
no sound.
The volume knob on the front does nothing I can just hear a little bit of hiss and a slight hum. The transformer is humming slightly.
The controls on the front seem to work properly, I can edit settings, when I switch from DIST to CLEAN I still get no sound from the guitar.
I am waiting for a battery holder from ebay and in the meantime I bought a spare CR2032.
Where should I start first to get this working? Once it does I will proceed with the noise mods and transformer upgrade etc.
Thanks in advance.
EDIT: I forgot to mention that at the end of the sequence it displayed an 'err' message but I don't remember the number. The message did not happen at the second power up.
