My Dynaco A25 stories: Have one pair I bought new back in late 60s or maybe 1970. Still have them, but the wood on top is looking poor. As near as I can recall, I paid less than $100 for them brand new.
Got a second pair for $10 at a church rummage sale. Lent them to my then-teenaged daughter. She thought I was giving them away, and put them in the lane behind the house when she got something else. Maddening, but I love my daughter, so...
Now have a third pair, mint in box, which were given to me by an old friend who was downsizing. Put my originals in the box, until I have a chance to use them.
I guess this just shows the "luck of the draw"
