Heated up the pins and engraver vibrated , while on the tester, and no
wavering or failure. So resoldered the pins and will try back in the amp
instead of SS rect.
Another thing I've never seen , one of the ECC83 valve bases is only
held on by one pop-rivet, the other rivet bulb is held in the valve base
ring, pulled thru the chassis hole, not been knocked, just normal valve
estraction force was enough
