Working on something new. It will be a rack mount preamp.

I call it a Sock Turlet Board.

Stay tuned. ;-)

This is Doug's version

No, your's is a mixed eyelet/turret board

I'm curious to see results

Ciao

What is the wire used to connect the turrets? I am looking to start a build of some sort and I have seen turrets connected like this on some of the Hoffman project info pages. What type of wire is used and how do you twist it to make it look so nice?

LooseChange · « **Reply #3 on:** March 11, 2012, 04:14:35 pm »

My board has the sockets facing up.
The wire between the turrets is buss wire. Strip 22ga. solid core is what Doug uses.

You can't quite see it in the pics posted, but all Doug does is twist them from turret to turret.

I think there are clearer pics of this in Doug's library of tube amps. It's at the top of the main page.

Alright thanks. I have some on the way.

I'm sorry but I don't understand you. "I have some on the way"?

daveyajd · « **Reply #8 on:** March 11, 2012, 11:00:26 pm »

I just placed an order for some parts, including wire, and they are on the way.

Wiring this board top and bottom is more of a challenge than I thought.

Top and bottom ?

are you trying a double face components Turlet Board ? or not ?

I was thinking you want to put the components in the top side and only socket connections on the bottom side

My curiosity about this your's new job increases and I/we are waiting for further news about

thanks for sharing this new idea

LooseChange · « **Reply #11 on:** March 13, 2012, 05:28:32 am »

Yes, exactly. Components on top and socket wiring under. I'm never a fan of bottom wirin g. I like to see where everything goes. But it looks pretty cool.

jojokeo · « **Reply #12 on:** March 13, 2012, 12:27:11 pm »

Looks good LC, the only concern I see is if you need to change or alter a component after installing. That would be a bitch to say the least. Maybe solder the bottom of the turret and if your stand-offs are tall enough the resistor or cap would fall away/off. Then you'd have to feed the new one down and up back into the turrets w/ some long nose needle nose pliers maybe? Then re-solder, cut & trim.

Is this a brand new build or something you've already worked out before?

Fresh_Start · « **Reply #13 on:** March 13, 2012, 01:47:34 pm »

Rack mount explains it... I was really confused there. Looks nice and a great idea for that application.

I've combined a few eyelets on a turret board before. It worked out OK but was a little confusing for me until I made the printed mask with different colors for turrets vs. eyelets.

Cheers,

Chip

HotBluePlates · « **Reply #14 on:** March 13, 2012, 02:10:05 pm »

Are you thinking about adding an insulator board underneath the main board?

I dunno exactly how you'd do it, but it would seem handy to prevent underboard wiring from falling away if you have to unsolder/swap parts.

Or... You do a little less-neat wiring, a la Fender, and have a significant length of the wire in inserted through the eyelet, then bent over. After sldering, and when trying to remove a component lead, the extra little hook in the wire end helps prevent it from falling out.

kagliostro · « **Reply #15 on:** March 13, 2012, 02:17:16 pm »

Looks Very Nice and practical

TIMBO · « **Reply #16 on:** March 13, 2012, 02:25:22 pm »

Hi LC, I have had little to do with rack mount stuff but the ones i have used have a removable top and bottom panel and the kit comes with metal rails, so could your board, transformers etc. be suspended rather than fixed to the bottom panel? Looks Good

Willabe · « **Reply #17 on:** March 13, 2012, 02:46:23 pm »

I think he's using a standard Hammond steel chassis and will add rack ears to it?

Looks real good to me LC!

Brad

jojokeo · « **Reply #18 on:** March 13, 2012, 02:55:27 pm »

I like it too but it's different from what I was thinking. Not sure why the turretts were mounted the way they are but it doesn't matter.

I think it's to lift the 1 end of the R's above the ground buss?

Yes, rack ears. BUT... Can't find anything that fits. They need to be no more than 1" wide.

Why only 1"? The chassis deeper than that.

Brad

LooseChange · « **Reply #22 on:** March 13, 2012, 03:19:13 pm »

The chassis is 17" wide. That leaves only 1" each side for the rack ears.

Willabe · « **Reply #23 on:** March 13, 2012, 03:38:47 pm »

Ohh, it's the width. I was thinking the hight of the face.

Willabe · « **Reply #24 on:** March 13, 2012, 10:05:45 pm »

I have a good friend who has a 24 track 2" tape full studio with all the old out board gear and the old mics.

He buys old studio out board rack gear and often has to re rack them. He does not like Hammonds rack chassis, from working with them, but loves Par-Metal rack chassis.

Here's the link to them;

Sure they can. I have a pair of mic preamps built exactly the way you describe, with a similar, but different, handwired board.

Do you have a link for the kits you're talking about?

TIMBO · « **Reply #26 on:** March 14, 2012, 02:40:40 am »

Hi HBP, This is my local Electronics store here australia http://www.jaycar.com.au/index.asp the 2 and 3u have i think four of these metal rails

EL34 · « **Reply #27 on:** March 15, 2012, 07:01:44 am »

I did a bunch of my early amps with sockets on the board.
Starting somewhere around 1993

Here's a few really old pics

Plus several of my rack projects including a power amp
It's a good way to go and fun to build

LooseChange · « **Reply #28 on:** March 15, 2012, 07:05:19 am »

That's awesome Doug! Wish I saw this before I built mine. :-)
Thanks!

kagliostro · « **Reply #29 on:** March 15, 2012, 07:12:19 am »

LooseChange job is one of the possible variations on the TCB (Turret Circuit Board) planned byDoug in the late '93

Two different but similar way to obtain a nice and practical Circuit Board

there is always something to learn from others

again thanks for sharing

All that and more awaits on the library pages.

All that stuff is in the Hoffmanamps section showing stuff I built way back when
