Re: Info about this marshall
Yup..SS preamp. Tube power section. They sound pretty dang good as I recall. I nearly bought one back in the day but ended up with a 50w all tube combo. I personally think this is a better mousetrap than tube pre/SS power amp technology.
The mods he mentions apparently are pretty common, and what most people "in the know" about these amps do.
With the cosmetic issues it has and the shipping charge, I wouldn't pay more than his opening bid tho. About $400 max is what I'd pay.
