I have 3 amplifiers here, the manufacturing/assembly dates are fairly accurate for the complete units.

1/ has many Erie caps, all are YYS assembly tag July 70.

2/ Hunts/Erie mix but same caps, Hunts A YI & W YA, Erie A YH, assb tag April 69.

3/ just two 8uf 150v Hunts MEW, no assembly tag but guessing 1966, other RS caps are PXH,PXJ etc
