I just finished casing up my PPA and I love the way it looks (and sounds!) so much... I just had to share it with the rest of you.

It's a pretty standard PPA, 627/637 combination. I added three Bourns trimmers to bias the opamps into class-a (thanks Doobooloo). There's a Velleman based power supply inside. I liked the look of the PPA Voodoochile made for Sovkiller so much that I used it as a model for mine.

This is really only my second project, but I'm suprised at how well it went together. I loved every second of it.

I wanted the power switch on the front, and most of the switches I found that were mains rated looked kinda like they should really be put on the back. The cool looking ones were usually only momentary, and had lousy contact ratings.

I decided after building such a nice amp, it was worth the extra effort to make the momentary switch work. I ended up building another circuit to use this illuminated Bulgin switch. I went ahead and added a pair of bright blue LEDs inside to "pimp-it-out" a little while I was at it.

Anyway... here's some pics. Hope you enjoy them!

OMG that is possibly one of the nicest PPA's I have seen!!

Wanna sell??

LOL

Beautiful. Love the case and that lighted Bulgin switch. Where did you find that case? I need one. I want to get rid of those ugly Hammond cases and combine my PPA and its power supply under one roof.

 

[ITZBITZ]

Absolutely. Gorgeous. Work.

I'm sure the inside is just as nice.

Superb attention to detail!

Terrific work! Where did you get that switch? Can you share the part number for it? Also, did you order a custom 17-inch wide case from Par-Metals, or did you just you with their standard 16-inch one?

Thanks for the kind comments!

Given your avatar, maybe I should ask for... say... one MILLION dollars!

GWN: The case is a Par-Metal case. It's the 20 series. You can get it in a number of finishes. There's a link in the Sticky: DIY Links Resource

Wodgy: I picked up the switch from Newark. The part number WAS: 91C6844. But I notice it does not show up there now. Allied has it... Part #: 566-0002. Bulgin's site is here.

The case I used is 12" x 8" x 2". Big enough for what I had to put in it. I did think about making it match the rest of my components, but I thought the front would look pretty bare if it was that wide.

Great amp! Professional looking work. The best looking PPA I've seen so far.

 

[spaceman]

That is some great craftsmanship there. Excellent job.

Wow, can we see the inside?

 

[Sovkiller]

Nice job man...Very nice looking amp, shame I didn't know about those switches before....I would like one, I just placed mine on the back as nothing was decent enough to be on the front, but those man, you killed me...LOL...!!!!! Great job....very nice indeed...

BTW mine right now looks very similar, no glowing inside, but the outside is all silver, I sanded and buffed it, ordered some stainless steel button head bolts, instead of the original socket heads, and ordered also a new front panel from FPE, that looks pretty nice, all countersunk, and with all the proper engravings, it looks like a vintage amp (to me al least, LOL) as soon as I finish it, I will post some pics....

Simply stunning.

Beautiful work Wooderson.

 

[Sovkiller]

how did you get the glow on the right side, on the left I could imagine that is from the switch, but on the right side...????

Gorgeous, absolutely beautiful! Congrats on a fine piece of work!!
