Anyone know how to read serial #'s?

[scottcrud]

What year would this rectifier be? R-011333 or RO812

 

[scottcrud]

They're closed till Monday....someone here must know...

not sure what year it would be, but that serial number means it is the 11,333rd recto ever made (at least i think...right guys? lol)

R-011333 would be later 90's. R0812 would be a 92'...posibly 93'.

R0812 would be a 92'...posibly 93'.

Are you sure on that?

Yes.

I agree with kung-fool...

 

[scottcrud]

so is that good? Does it have the original transformers? or does that have to be the first 200?

812 will not have the original transformers. 503 and below will. Plus, you even run into different circuit board revisions even within the first 500.

read the threads "rectifier lineage" and "dual rec tone test"

My mark IV is a IV-0111?? . This is a 2002 amp. Sorry I can't tell you the last 2 numbers. Hope this might help.

My 5-97 DR was R008525 and my 6-99 TR was R-012894 ... so...
that's 4,369 made in between....
that would make the R-011333 roughly @ mid-late 98 ? I'm thinkin :roll:

My 1-93 is R-001109....so the R-0812 would have to be late Oct/early Nov..ish? 92

It's funny 'cause I have some inside shots of the chassis (true amp porn) and the smaller PCB has 11-5-92 wriiten on it and the small relay? has 11-18-92 written with Wiley signing off on it. Revision RF-1F.

I'm thinkin' it was almost ready to go in December and they took the holiday break.
