Bassman Ten dating [Help!]

[Stan6889]

Hi there guys!
I seem to have issues dating properly
I'm trying to find out what year my Bassman Ten was made.
I've looked online but can't figure it out.

Chassis says: A 798xx
Transformer is pretty rusty but reads:
J022806
CSA Tested
60?-4-16

Tube chart and spiders:

Thanks for your help and have a nice day!

Stan

The transformer date code points to 16th week of '74. That adds up; they only produced Bassman Tens from '72 until '77...after that, they were updated with 3-band EQ on both inputs and were Ultralinear - rated at 75 watts instead of 50. Edit: Note that the date code is for the transformer, not the amp itself. Still, it seems more than probable that it was sometime in '74

This serial number decoder at Guitar Insite returned a bunch of possibilities -- none of them Bassman Tens, but many of them from 1974. Fender Amp Date Decoder - GuitarInsite

Where did you collect the information regarding the period these models were produced?

There are a ton of sites like Ampwares and that Guitar Insite site I linked to earlier -- they're both good sources, but there are others. I happened to have that data in my own personal organic storage unit, but the years of production for the various Bassman models are on the Wiki page for "Fender Bassman".
