18Vac seccodaries, 25Vdc caps enough

Built a board to hold a couple GBJ3506-BP rectifiers

 

[Zen Mod]

best to bolt them to bottom plate
proper and simplest way to keep them cold

thermal goop and split washer, must

 

[Monk55]

Kinda tough to do that….but there is a hole….hummmmm

 

[Zen Mod]

KBPC3506 or KBPC5006

you're asking trouble with these Lilliput ones

 

[TungstenAudio]

The inline leaded rectifiers can work in the upright position with a little help..
I have these in my Aleph J; they do run pretty warm, about 55° by the Papa scale.

ZM is still correct; the baseplate of a chassis makes a good heatsink for the brick style rectifiers.

 

[Monk55]

TA, what’s the specs on that baby? The one I’m looking at is 600v, 35a. Will bolt to bottom plate. Thanks

 

[Zen Mod]

ZM bitten too many times, to even consider using small plasticky drek in any amp drawing 1A5+ per channel and having ooomph caps

35A is smallest bridge ever going in any of my amps

 

[Monk55]

Glass Passivation (melting glass) is applied at 800degrees I think. Should be pretty good. Guess I’ll find out.

The LVB2560 is rated for 25 Amps. I used four of them in the dual-mono supply for my Aleph J.
The large CRCRC PCBs that I used left little room for chassis mounting the rectifiers, and already had the inline footprint.

I prefer more something like this...

Are they really Screw Terminals as Mouser says? I love Screw Terminals.

 

[TungstenAudio]

The GBPC series rectifiers use spade terminals, not screw. I only use these for ground lift circuits.
Here is a different series of high current (60A) rectifiers that can be used with larger amps. Screw terminals, chassis floorplate mount, and still fairly low Vf.

 

[Monk55]

Thanks for memory spark. That’s the one I’ve used before. Just couldn’t find it. Spendy little buggers. They sure make excellent terminations.

 

[Monk55]

And so it begins….thanks to Mr. ZM.

Salt, pepper, sugar. 😎

you know your way around CCS Daughterboards?

I mean,there is only left for you to solder LM334, BC556 and trimpot, all being in bag with pcbs

and then, be sure to solder them with copper studs at least 5mm elevated from main pcbs

just a reminder ( for me, as first) - this is R.3 thread, while you have lastlast blingy - (42)

Holy cow……I just read. Learning the ways of the mighty ZM is taxing & exciting all at once but nevertheless I remain diligent. I have so much to learn….”I’ll be Bock”.. 🍻

 

[Zen Mod]

you can't even imagine how exciting is being me, 158hrs/day

 

[Monk55]

You must really enjoy the SHI@ out of it as your approaching 50,000 messages!!!
I for one am very glad their folks like you out there.
