Hey Martin, what is your reasoning for this?

Yes, xtian, kudos for choosing clean response words. It makes you look as intelligent as you truly are. Also, great suggestions from the lot of you. I think you have done well with your responses, getting to the point quickly. You must feel some comfort with your messages hitting the target. The onl...

Hello -- If someone wants to post the preamp board dimensions from a blackface or silverface [ ... ] From my 1964 AB763: Overall board dimensions are 14 5/8" x 2 1/2". There are just three bolt through-holes for mounting. These are slightly misaligned across the longer edge. Starting from the power...

That is where I take it another step... Spray it with black paint and then block sand it.

If someone wants to post the preamp board dimensions from a blackface or silverface, I will rearrange the preamp parts to fit and produce a second set of files that correspond.

Looks like a serial number

Reminds me of my aloha... Down to the topology and the motb

Very, very nice! I had to do a double take.

Hey, friends, I'm on board as TAG admin. (Power corrupts!) There was a big backlog of folks wanting to become members, and I've let many of them in just now, so I'll be watching out for shenanigans and spam. Carry on, and happy holidays! Oh lord, there goes the neighborhood! Just kidding! Glad to s...

Yes

As you can see from the files below, part of the board wasn't populated. I cut it short. The pdf file is 1 to 1. Print and use how you'd like. T...

Yeah... It is just what I needed for this. The job and holidays are delaying me further. I already have a board layout done. I'll see what I can get posted when I get to work tonight.

How about now?

Yep... The dimension didn't come out as 2 1/16"... So I posted it as it is. No worries, I can wait. 2 1/16 + 3/16 + 3/16 = 2 7/16 or 2.0625 + 0.1875 + 0.1875 = 2.4375 Add another 1/16 in there and you get the 2 1/2, or so I assumed. Then there is the other end too... :roll: Tell me what I screwed up.
