Hello all,
I was inquiring on two things.
1) Any one know of a good source to find 10 lug terminal strips?
I saw some new on ebay from China but they don't look anything like the vintage ones.
2) This might belong on the cab building side but...
In everyone's experience (I believe this is going to be 50-50 and null) Im assuming if done properly--both are fine--but I was going for least headache.
Was it easier to create box tails with table saw and jig OR router with box/dove tail jig (like Porter or cheapo at Harbor Freight)?
Lastly, it's pretty awesome when we got 3 AC-15 builds going on. I really can't wait to hear the results.
Best of luck--Ed, Sluckey and Lego.
Thanks

Myself and a few others have that one and like it.... if you already have a router?

John,
In terms of those terminal strips in a point to point amp, if the circuit I have seen utilizes a ten lug but the grounded lugs are the first and last (1,10) would it matter or could I work around using those (surplussales) with the grounds at the second and second to last lug (2,9) or should they match?
The home depot jig. Im still undecided at this point. I will be borrowing nearly all the tools and unsure if I want to go out and buy a jig for a router that's not mine.
Thanks for your help and links,
Matt

I'm the wrong one to ask, I've never used any 10-luggers before. I'm guessing whoever did the layout used what they had on hand.

There are some sellers on ebay who have these (don't know about 10-lugs) but they aren't cheap. I have bought terminal strips on ebay of Russian (I think) manufacture and they soldered like pure crap. Very poor solderability. That doesn't mean every Russian everything is poor solderability, but these sure were. Terrible. You don't see these new, from domestic manufacture very often, as you've discovered.
CONN tube organs will yield about a dozen of them....next time you see a cheap CONN for a giveaway price, add that into your evaluation of 36 qty fairly low-value 12AU7s and a few actual useful tubes. Of course you have to desolder them and demount them, either by drilling out the rivets or (my preference) grinding them off)

What's the magic of a 10-lug terminal strip? The longest commonly available length is 8 lugs, with the outer two grounded.
Or do what I did and make your own. I cut some of Doug's board material to an appropriate length and width, installed the number of turrets I needed, left room on the end for mounting hardware.

Eleventeen,
Thanks for the tip on the organs. I am not familiar with all the specs/guts considering those and hammonds but it is worth checking every once and a while to see if anyone is dumping something worthwhile for reasonable cost. It pains me to think about trashing out something massive though just to take a few minor parts from the inside. Wouldn't know what else to hold on to besides maybe speaker and switches possibly. Kinda reminds me of those idiots that cut off the shark's fins and then just dump the whole thing back in the ocean. But I guess if the whole thing was going go to go out anyay at least something got saved.
My wife is from eastern europe and I came across many russian PIO caps and other parts. I was tempted to purchase some but nixed it considering dilemma of taking them on the plane possibly. I assumed the standard was there but then again black market is rampant and I wouldn't be able to spot a fake from not too. I wonder if L. Fender would ever cared to have russian stuff in his instruments.
HBP,
that is a really cool tip that I never thought of in terms of making your own strips.
Thank you

Yeah or kill a rhino just to grind up it's horn and drink it in tea for supposed male potency, meh! :BangHead: :cussing:

Back then he didn't need to, we (USA) made what ever he needed. Now? Even though he was a businessman I'm not so sure he would be to happy about that? But who knows?

Yes, I've got real long terminal strips in my Cordovox organ cab. But the work involved in de-soldering the old components & drilling out the mounting rivets makes a new terminal strip look very attractive. Torres Engineering used to carry long terminal strips, but I don't see them on that website anymore.

HBP,

Exactly. Essentially, I have a 19-lug terminal strip for the long lower one, but with turrets. Terminal strips would not have made the amp any worse, but the way you need to wrap the component lead around the lugs on those strips means changing a part is a hassle. It was quite easy to change with the turret strip, which I had to do with some caps to voice a control properly (turns out I didn't consider all the factors when I calculated the needed part, and cut/try by ear was a very fast way to correct the control's action).
