Not sure of the year probably late 90s early in the production run #66. It’s definitely a tube amp , loud and proud circuit construction like soldano. It’s a two el84 power section with a three x 12ax7, one at7, pre. Solid state rectification.
I bought a Zinky Blue velvet at the Orlando guitar show!
had it about a month, really like it!
Both channels are easy to use and really rich, great reverb, oh.. and for 25 watts is incredibly loud!
good thing it has a master volume!
