'HP' is for 'Head Pirate'!!! - HEAVY ON THE PICS!

So a couple of weeks ago, I got a box full o' parts from Captain Jenrick, Head Pirate and coil winder extraordinaire. After a minor setback in the building process, today I finally got a chance to put these puppies together, so I took some pictures and documented the assembly process for your viewing pleasure. I know Chris did a similar page, so this is a little redundant, but what the heck... Enjoy!

'HP2503' ASSEMBLY:

It all started as a bunch of parts:



First I took the wires coming out the coil and burnt some of the varnish off the ends:



Then I cut the leads to length and twisted the wire around each one:



I soldered everything...



... and I taped things in place and bent the leads to create a strain relief of sorts:



Some tape holds everything in place:



Then I took a long piece of tape...



... and wrapped the coil with it. Coil is done!



Put in the E lams:



Put in the I lams:



After banging everything with a hammer to make it nice and tight, I slipped the core in the U-frame, held the whole assembly in a vise, and banged the tabs down to hold the whole thing together:



Ta-daaa!



Special thanks to Chris for all his efforts!!! :thumb: :sam:

Now I gotta hook them up and try them out on something...

Peace,
Al.

Great pics, thanks Al.
Bookmarked.

Right on, cruton! :thumb: :thumb:

nice job !! :shock:

Holy Sheesh!

If they don't work, I'm toast around here.

Nice job, mo!

:thumb:

Cool, almost done!. The final step is sending them to my address. :razz:

Seriously though, where are those going to go?

Miko,

I have way too much crap on my bench: a couple of mics that I haven't had time to get working, a bunch of preamps, a VCA compressor... I got ten channels worth of P66's that have been sitting on my bench for literally over a year waiting for gain switches and output transformers. Now I only need to get the switches :thumb:.

Peace,
Al.

Way too cool! :thumb: :thumb: :thumb:

Hi!
How much can be parts (kit) for one or two transformer and where to find?
I need a pair!
Thanks
Duka

Now I can finish my Fabio 312!!!!

I'll let you all know how they sound when I get them done.
Just ordered my grayhills and input trafos today.

Looks good ! :thumb:

And interesting to see CJ is a model :grin:

Wow! Looks sharp!

Let me know if any suggestions for the instruction page.

Maaahvellous stuff chaps.... :thumb: :thumb:

Al and Gary--nice job!

Looking schmick gents!

I found a company that makes adhesive backed copper foil:

http://www.chomerics.com/

specifically:

http://www.chomerics.com/products/documents/tb202.pdf

I believe p/n CCH-36-101-0100 would wrap around the 2503 nicely.

I have yet to do tests on the merits of the copper foil. It might just be for cross talk between channels, it might be some type of capacitive tweak to balance coil/core capacitance.

Hi
I start to assembling transformer. Maybe stupid question:
Is important E and I lams orientation :?
Duka

its not be stupid :grin:
Keep all your lams facing the same way. There is always a little burr on one side, and you should try to keep these burrs facing the same way so you get a neat stack
I did it :!:
Only I am thinking about two solution:
First- to build like original Api style transformer with copper foil
Second- with U bracket
Duka

yeah! good job duka! :thumb: :guinness:
i guess the only reason you would need the channel mount (U bracket) would be to mount the xfrmr off the pcb and on the chassis.
if you're mounting on the pcb then use the nice copper foil.
