Mark II chassis designations

[Michael Italia]

What do the different Sharpie marker designations mean on the side of the amp chassis? I can interpret some easily, such as R = reverb, G = graphic equalizer, H = hardwood (?). A Mark II A I have has SSQ on the side. I've mainly been a Mark I RI player until acquiring the II A, a couple II B's, and a II C during the last few months, so am learning a bit more about the amps construction and tone. Thanks

H = hundred, not sure on SSQ. If convention is like later amps, the first S would be sixty

check out the IIC+ guide for dummies it may be helpful, doesn't help with SSQ exactly. Got a pic of it you can post?

SS = super sixty on some of the early ones
you sure it's a Q? They may have been playing Q-bert while partaking in N Cali medicine and made a mistake.
Normally just S, SS, H, D (simul), K, R, G, X (export)

Thanks everyone for your input! Makes sense now. That "Q" is probably a "G". I'll check it more closely next time I need to open it up!
