    Thanks. I found a site that claims its Accutronics 4DB3C1D. Revisit makes a comparable tank, but I'm going to sit on it for a while, see how I like the amp first. I don't use a lot of reverb, even on my Fender, but I do like just a bit to liven things up a bit. We'll see -- thanks again!

    The site you found is correct

    I ended up just putting a Holy Grail nano in the effects loop and it does the trick. It's not an amp that sounds great with soaking wet reverb, but it adds just enough texture to liven things up a bit.

    A quick question -- When I'm looking at the back panel of the amp, all the way to the right under the serial number where it says "CODE", there's a small metal toggle switch. I have no idea why's it's there, and when I've looked at other photos of the amp, I don't see it -- in fact, I see red & black wires entering the chassis in that area on other photos, which I assume are the in/out for the reverb tank, which my amp is missing. Any thoughts?

    It's a mod. The switch most likely removes C13 from the circuit for better tone. Most people like myself just cut the cap. The switch gives you the option to change it back to stock.

    I'll have to open it up and take a look. I already cracked her open and clipped C13 on my own -- didn't notice anything "extra" there that would've hinted at a bypass mod for C13. I'll email the last owner, too.

    Finally remembered to look into that toggle switch -- it's a channel switcher! It was fun to mess around with the boost channel a bit and dial in some real Marshall crunch, but I'm pretty happy using the clean channel along with a complement of good dirt boxes. The Hotcake sounds amazing with this amp. Still, the Marshall boost channel could come in handy for recording a solo or two in the future. We'll see.

    I still want to put a 12AT7 in the PI position to see what I get, but I've been really pleased with the stock 12AX7 so far.

    Hate to admit this because it makes me look like an IDIOT, but I've also had occassion to be directly impressed with the durability of the components. At a gig last week I had everything all plugged in, guitar through pedalboard with guitar volume on 10, plugged into amp at stage levels and I wasn't getting any sound. Like an idiot, I strummed away while I fiddled with things and it took me several minutes to realize the speaker had come disconnected at the terminals, so there was no load present. That's a recipe for disaster, but this little amp shrugged it off and hasn't showed any signs of damage. Feel like I lucked out on that one!

    I found a Craigslist deal of the century for my 3203 head and matching
    1966B 2x12 cab... $275 for both in excellent condition! I've been playing for 40 years and this is my first closed back cab... goosebumps.
