Rat fur, non-original knob and presumably switches. Missing caps and pre amp tubes, 6550 conversion, but all there otherwise. I will lovingly restore this thing complete with 6146B's.

You bet. This was a nail-biting ebay affair so I don't have it in front of me just yet but I will take an exhaustive photographic survey when it is. Needless to say, I am excited. As some of y'all are aware, I collect all-tube Ampeg gear and this is the holy grail!
The 69 had the unpainted chassis so it allows you to remove any rust. The feet had the vibration pads mounted to the cabinet. The oldest SVT and the SBT are the only two that have that feature as far as I know. Anyway, the vibration mounts have a date code on them as the pots do.
You have a lot of work ahead of you but it'll be a lot of fun.

It is a standard octal socket. The time delay relay is an Amperite, you can use a G series 115NO30 (the 30 is the delay in seconds). It costs around $25. You would be better putting the tube aside and installing an octal plug with a jumper installed from pin-5 to pin-7.
May I just ship it off to you, Mr. Toast?
I can answer any questions that you may have.
Is this the tube socket at far left in the back of the amp? It its function to delay full power unti lthe tubes warm up?
I recovered my old SVT amp just like this one, as a matter of fact, it looked exactly like this one w/ black grill clothe. Never knew exactly what year it was but I knew it was old as the matching cab was a square back like the kind they had w/ two cabs on a dolly. Probably a coincidence it would be my old one but who knows, these tend to get around in there lifetimes.
Yes, it is in front of the transformer. Turn on the power and it delays turning on the high voltage. It acts like a standby switch. If the tube blows at a gig, you can't turn on the amp.
RE: the relay socket, they are almost always modded with a shorting plug between two pins in its place because the whole amp goes down if the relay tube goes down, as Beans states.
RE: the 6146b's, I would be tempted to leave it with 6550's. I don't know that it makes a whole lot of difference. My Heritage and my 69 sound pretty much identical when the Heritage's master is dimed, and if there's any difference at all, I can't spot it. But then again, NOS 6146b's are cheaper than 6550's and they're cool as all getout, so maybe I would mod it back

Huh, Jimmy, thanks. That makes sense. Maybe I'll keep the relay, but run a circuit from the two pins to the former polarity switch; a relay bypass if you will. Or I could just carry around a spare relay. Funny, I like the sound of the relay....neat that the amp can't come on until it's a tad warmed up.
Well if you do the shorting plug, it'll do a 30 second relay anyway. At least mine does. And I wouldn't want to be taking 14 screws out of the back of that amp on a gig when the relay craps out!
The auction expired at 9:03 pm last night. I had a gig - downbeat at 9. My sweet girlfriend put in a max bid of 537 dollars with a minute to spare to diminish the chance of someone increasing their max bid. Earlier, I had actually told my band mates and the guy that books us there that we were going to start about 5 minutes late. It was very exciting. The final price ended up being $514.50, I think.
