ampeg js-35 fountain of sound tube amp rare vintage

this rare piece is in great working condition,all original too  ...the speaker and power cord look like there from a new amp there so clean and supple...sound/tone is strong (like an amp that was barely used) pots are perfect no scratchiness ..s/n 909067..the cover is as pictured(a little tattered) and the grill has some discoloration spots ...no other issues ..we are firm on the price ..so ive gotten some emails regarding the speaker(guys claiming its a mid 60's and the amp is a late 50's) this was a one owner amp..ive spoke to the original owner (pro jazz guy in the 50's and 60's ,based in philadelphia) he assures me that he ordered this amp from ampeg via a local music store ..after seeing johnny smith using one..he claims the speaker was never changed and this is the speaker it came with from ampeg..i dont believe the guy is lying and he seems of sound mind.. but im sure some "experts" will beg to differ
