10,000 Series 67' Superbass

ok hows this?

[Roe]

better but I'd twist the secondaries as well. and don't run them parallell to other wires (red, blue, black)

10-4 Roe thank you! I will take your advice and take a picture of it when done to see if I get it correct.

I am guessing these secondary wires that connect to the Ohm selector are sensitive, yes?

I couldn't figure a way not run in parallel with those other wires so I moved them to the other side of cap board mounting bolts. You think I will be ok?

Do I put a jumper wire between the positive side turrets of the bias caps? One side goes to ground, is the other just picking up a ground from that jumper?

Still unsure of this.... Area in question is the black jumper on the turrets directly behind the Mid tone pot

Here is what it looks like so far.....

Yes it is a ground wire. I would not insulate it as you will need to solder one leg of the bias pot to it.

Thank you sir!!!

ok so according to the 67' 100 watt board layout diagram I see two 10K 2Watt resistors in parallel and across the dual 20 capacitor, at the middle of the PTP board. It appears according to the diagram that these are Metal Oxide resistors, but I see on George's photo's of his 10,000 series he is using Carbon Film. Does it make a difference what type I use as long as it is the correct size? All I have handy are the Metal Oxide....

Also, I am using 2 16uF caps for this position. What is the difference in using the dual 16/16 vs. the dual 20/20 vs. the dual 32/32?



Thanks again guys. On the home stretch now and getting excited to fire her up!

On a 10 series you will have a 10k and 8k2 dropper in series wired after the screens cap node (same hook up point as the choke 'out feed' and before the PI cap node. Trace this bus wire to the PI plates feed and then to the first of the 10k droppers that crosses the board. One limb of the dual 32uF can (or sounds like you are using dual 20uF) is hooked up to this as well as the blue V2 plate feed wire, then the other 10k is mounted either on the board (stock) or just hanging off the board to the next turret back along, the other wire on that is the bus wire that takes the feed to V1 plates.

Look at this pic of the Dickinson Hendrix 45/100, it is exactly the same.

2watt MO are technically much better spec than the carbon comps as they are flame prrof and less prone to drifting up or becoming noisy when they absorb moisture from the atmosphere. CC can hiss and crackle, good for vintage vibe only!

Looks Great, did you get that board from me?

You bet I did!!! Thank you... I also referred some guys to you, so sounds like you're gonna be busy!

OK so how does everything look so far? I am currently waiting on the caps.... I ordered directly from Sozo over a week ago, and I have heard nothing from them? I hope everything is going alright over there? I noticed their website indicates they were out of stock but then they had expected time of May 5th or something like that? I emailed them as well but no response? Looking forward to getting those!

Anyway, I am also going to be asking for some help in the tube department, but I posted in the tubes section.

So here it is let me know how she looks and I have some questions for some of the photo's.

1:

Gut Shot so far



2:

Shot of the Bright Channel Mix Cap and the tone stack treble cap. Axeman (Art) gave me these cool looking sprague capacitors. what do you guys think? I noticed the values are different than I have seen, and also the voltage on the Bright Channel Mix Cap is 300V, is that ok? I don't think that see's much voltage does it?



3:

Here I have a question about the 2 watt Metal Oxide resistors. The 10k and 8.2K in the middle of the board with the dual 16/16 filter cap, and then again near the bias section of the board. Is that correct. I see most of these 10,000 series with just one 10K or one 8.2K near the bias section of the board? Then with the dual cap in the middle of the board I usually see 2 10K's? I am a little confused on this? Can someone shed some light? (p.s. I just moved one of the 16uF caps out the way for the picture)




Also, all I have for left diodes are HER108 616 will this work for the bias diode??

Also I have a 56k ready to solder to the bias pot, is that a good starting point? I have seen some people use 68 k or even 47 k. I suppose as long as I get in the range I will be good and I won't know that until I get some readings first.

thanks for all the help thus far fella's, we got a gig in one week, and I hope I can use her.... I doubt I will get her done by then though.

OK I gave up on Sozo for the time being.... No word from them and no response to my email's, no shipping details or anything.... If they arrive I guess I will just have to build a 45/100!!!

I found on tubedepot.com they say that Sozo has discontinued making these? If that's true that would have been good to know before I purchased them directly from their website! Oh well.... I hope that's not the case, and I hope they just show up one day?

It's quite confusing as I have asked similar questions. Sozo seems to have discontinued their *Standard* line of caps, but they still advertize the Vintage. The Standard(s) were offered via different distributors.
The Vintage caps on the other hand have only been available from their Website, so that's apparently what you ordered. They're great caps, so follow up on your order and hopefully you'll receive them.
