[BUILD] Tr1dent A range PCB support thread

[pH]

I'll try to get pics once it's a bit more buttoned up, mad alligator clips, flying leads and blue tape removed etc.

I'm kind of surprised at how different this sounds from my other SS pres (Neve and API style). So clear and open on the top. Great stuff.

Peterc - how do you get the higher voltage (44vdc) out of the 500 series power?

I didnt...

Just rebiased the output pair to work on +-16v.

Hi there, there are some pictures of the troodent A-range I built a few months ago here :

Sowter in, carnhill out, I'm very very pleased with it, 4 more to come soon !
Thank you Grand Master Audio for this amazing sounding preamp !

I wanted to add an output attenuator to this.... was thinking of throwing a pot between the output transformer primary, signal to wiper. Will this work ok, or is there a better way I should go about this?

@ adeptusmajor . Im not sure that's an ideal solution.

Essential the 2gang switch pot in the project affects the mic and Line amp stages, you could try separating these two, one control for the mic amp, and the other with more control for the Line amp. If you look at the schematic should make it clear.

@All.

Also i am making a few A range EQ PCBs for myself and a friend to build, only very small number of boards just for personal use. And i suspect i might include the mic amp too.

If a few of you wanted a board im sure ill have a few spare.

Thanks Pete - I got the idea looking at another preamp I built but wasn't too sure about it. I already have the two gang switches, might just build this thing straight up and try an outboard attenuator to see if it is worth driving harder.

Moring all,

Is there a schematic for the PSU sections of this project?

 

[user 10827]

@ adeptusmajor - go for it, no harm done.

Hi Emtee - Ill have a look when I get home, but do you have the original circuit diagram? if so its identical to that. let me know if you need any further help.

Best

Cheers, all I have is the schematic from the pdf build manual.

Thanks

Hi Pete!

I'd love a pair of the eq boards if you have enough...  that would rock

thanks

I think I will be in for 3 eq pcbs and some more pres in spring next year, if they will be still available.

 

[jandoste]

2 boards please
wow!

Thanks

Hi Pete,
I'm in for 2 eq pcb's if there are some left,
thanks a lot !

 

[museic]

Pete,
I'd also love a pair of the eq boards. Just getting started on the pres!

 

[pH]

Please count me in for a pair as well.

Hi Grandmaster, I'd also like a pair of the new boards.Thanks.

Hi
I would be interested in 1 EQ pcb.
If there are any left.
Thanks
