Hi Gary,

I just pulled the tubes to check the numbers and from left to right ( as per the photo ) they are:
80, 45, 45, 56, 224, 224, 224, 24A
The link you sent for the SM-60B is a close match but that model only has 7 tubes in total…mine has 8 ( an extra 24A )…so I can certainly use this for reference and a starting point.
The model I have also has a phono input terminal ( two pins )…
