The 68s, from what I understand can be 10 or 12 series. Starting off as 10 series, then 12 (EVHs amp), then back to 10k for the end of 68 and into 69 until mid year when the metal panels started and the serials changed to letter A + 4 digits. 68 super leads have the 2 cans up top like yours (and mine) and 4 underneath. 67s, I think had 1 can up top for a while then maybe 2. 67s can also be 10 series so it's hard to really nail down a later 67 from an early 68.
You can also date the Mustards/pots though, and if they date to the beginning or middle part of 67 it's probably a 67. There's a super knowledgable dude (more than 1 of course) on the Marshall Forum who has notes as to what color lead wire was used, brands of resistors/caps etc for each month of certain years of Marshall production.

I will have to do more sleuthing next time I have it open. The original caps are in a bag somewhere, should look at the date codes. The 150uf mains caps are 67, not sure month or week.
One site I was looking at said 10,000 was 67 12,000 was 68. But could have been partially right or wrong info.
My Metalpanel 69 has the A plexipanel does not.
I forgot I did have a 68 Supertrem 100 for a short time. It had a box fan cut in the side and kept shocking the crap out of me so I took it back. Way before I learned how to work on them.

My 69, the ghosting was so bad I had to up the mains filtering from 32/32 350v to 50/50/500v. Solved it. The date on the TCC cap was the 4th quarter 68. Jives with it being an early 69.I will have to do more sleuthing next time I have it open. The original caps are in a bag somewhere, should look at the date codes. The 150uf mains caps are 67, not sure month or week.

One of my old bands had a reunion gig back in June. Outdoors, brought my 72....I used to put a foam cover over my vocal mic to protect against possible shocks. Well, I forgot to do that and BOOM! Got zapped pretty good right during a chorus

I just read that the early 68s could have 1 can cap on top...so if yours has 2, definitely a 68. They are the most desirable of all the 100w Marshalls because of the EVH reference.I will have to do more sleuthing next time I have it open. The original caps are in a bag somewhere, should look at the date codes. The 150uf mains caps are 67, not sure month or week.

Great condition, unmodded (except for filter caps of course) can command 5 figures. Total museum pieces with all original parts, 20k. Maybe more.

I was just looking at the caps I took out of the Super Trem. Two axial 32/32 450 marked TCC and one RS 32/32 can. I know there is another somewhere. Tried to find some date codes, not sure what they might be.
The Mallory 150uf I am thinking are non original, but have always been in it since I bought it in ‘89 off a friend of mine. They are marked 677-88xx. I was thinking the 67 was 67 but now I think they are ‘88. I temember my friend saying something about big caps when I bought it. It probably had 32/32 450 for mains also.
This Super Trem doesn’t really ghost. The 69 Metal has always, this 78 2203 I just picked up ghosts alittle. Gonna put 100/100 in it maybe this weekend. I already recapped it and redid all the grounding. It is my experiment, play around with amp.
My SuperTrem was already missing the trem board, footswitch jack and now has a replaced PT since the bias winding went out. May get it rewound some day and put back in. It is a pretty good sounding amp, but not near as good as the 69 plexi.

The ultimate boutique candy store! new and used amps ( vintage marshalls and fenders galore, friedmans, two rock, carr, synergy, fuchs, diezel, fryette, red plate) /new and vintage gtrs/pedals/rack gear/acoustics/ukuleles….Loos like a nice little man cave indeed

Reading up on ghosting, there are quite a few causes for it. Mostly low filtering though. I was lucky in that just upping the mains filtering totally solved it. The sound was so bad, it was like a broken chorus pedal. Mostly on the A, D strings below 12th fret which is different than most descriptions where it happens in the upper register. Everyone chases the 68 SLs because of Ed; but I've read about so many great sounding 69s that I think they may be the best year to have. This one here, I wouldn't trade it for any other Plexi. Aggressive yet sags just enough. Great sound. As much gain as a lightly boosted 2203...anyone who doesn't believe these amps can have a nice amount of gain plugging straight in, needs to hear one of these 69s.

Lucky for me I hate the VH sound so ‘68 isn’t a must have for me if that is the big part of his sound
The ghosting drives me nuts. Pretty much every stock 100 watt Marshall does it. Even if someone claims they don’t as soon as I pick up a guitar and play thru it, there they are.
This 78 2203 does alittle, much better after regrounding it, but still alittle. I have some 100/100’s to try so might as well.
Even my brand new 1959RR did it, that was a bummer!!
Yeah like we have talked before, my 69 plexi is my holy grail amp. Did so many gigs with that one.
We played last Saturday and I took the SuperTrem, Ps2 and some pedals. Ended up using my Wizard as usual, maybe next time will plug the loaded Marshall rig in.
