Gibson Family

I posted a photo of my Gibson Les Paul earlier but I came across this photo w a Gibson amplifier.
On my way to work one morning it was trash pick up day and I saw this amp sitting ontop of the garbage can. I pulled over and took it w me to work. It is a 1966/68 Gibson Minuteman GA-20 RVT. I brought it to a friend of mine who specializes in tubes,, etc. He changed out the tubes, replaced the original power cord only. Amp works well as I've used it here and there. I paid $100. for a trash find amp that works and now added to my Gibson Family. These amp's are in the area of $500-800. depending on condition.
The sticker on speaker shows it was purchased from Providence RI (I forget name of store as amp is tucked away in storage).
