My first post here from an old Dynaco appreciator (my dad and I used to biuld kits in the late 60s together). I came across a pair of near mint MKiii's, the condition is truly remarkable, no pitting on the chrome, laminations on the trannies look like they were painted yesterday, 100% original down to the screws, boards, covers, even the boxes.
While inspecting the amps during the purchase I tested 4 of the all original Dynaco branded tubes and got near perfect readings on them. I'm presuming they are all in top form!
I'd like to maintain their value given the state of originality, while updating parts that will bring the sound up to snuff, what do you recommend?
Also if you have any experience in the value of these given the described condition, I'd appreciate your opinion on tha too. Lastly how would I identify there age?
