I also have some of these Old Schooool Audioo boards on thier way "unstuffed". I will scan them one I get them. These are 500 series preamps.

BTW.. I also have the Melcor EQ-20 on the way to me. It is the same as the GME-20 but adds iron, and looses the selectable freqs on the lower band. I can probably take some scans of that too...

Regarding the tran$ient De$igner, would you consider doing the entire JH Transient Gate with random/humanise function? Reading his design notes, it sounds like a pretty funky addition to the rack to me. I guess you'd need his permission, but he seems like a nice guy.
 
Call me crasy, but this chain would be great:
Q8-553-TD-Comp (even rogers THAT) - and make it fit in 1RU. :green:
I'm thinking drum side car.
Doesn't hurt to dream.
but just TD would do it for me.

Those GME-20 look very interesting. What do they sound like?? (broad question, but do your best)
 
Melcor GME-20 EQ = awesome!

Ok, first with the 1731 Opamp they are much smoother than API, yet sill punchy sounding. (not quite as aggressive as API). Two bands each have a switch with 4 freqs to select from. Also a Hi and Low pass. These are one of the first eqs that I know of (I could be wrong) that have the semi parametric Q that gets more narrow as you boost or cut the freq. So they start out quite wide and get more narrow as you boost. They become very narrow at 12db of boost. Also, there is no loss of level when using these. Most eqs when inserted drop the db level by a few. These do not. These do not have transformers, but are 600 ohms in and out. They play well as is, unballanced. Adding Transformers seem to only help ballance and add no real benefits. (But I guess the right transformer could add color). IMO they are not needed.

These are killer on kick/bass with subtle boosts. Electric guitar is freak'n the tits! You can boost one band like 12db, yet it is narrow. So it sits in a mix yet cuts through like nobody's buisness. Joel Hamelton and John Noll from Tape OP turned me on to that trick and works brillant. On Vocals it can add air, or de-ess pretty naturally, while at the same time can give a gentle boost to the low-mids to fatten it up.

The Melcor EQ-20 I have comming do have iron in them and are smooth as butta. They are limited by a fixed bottom end, and only 2 adjustable bands.

Sure, as was added right away when Juergens version was mentioned for this proposed PCB, he should be OK with the use of his design-additions.
In case most people are not into the added goodies that Juergen added and the stock version results, then only permission from S*P*L should be obtained :wink:

From memory there were a few corrections to the originally posted schematic (thanks IJR(sp?)), but I thought those were only component values.

Yeah! send me your paychecks ya all! :thumb:
Tomorrow I will quit my job then :green:
 
[quote author="Bauman"]I got an OK to go with the modded version pcb gentleman! :wink:[/quote]
Good news :thumb:

If this all starts to roll, then which version would most people prefer ? The fully 'pimped' version (so including the additions from Juergen) or the stock design ?
I'm in for the one with Juergens mods.

Bye,

Peter
 
I vote LA-3A !!! But this probably isn't the easiest PCB to make... and I guess transistor availability might be an issue. But it would definitely kick ass.
 
Pls guys consider Tr%ns*@nt D*s%gn$r out of the voting list...

I still have an eye on this thread :thumb:

Paycheque forwarder function:
bank account -> paypal -> Gil -> Fabio?
We are mad people, aren't we?
:grin: :shock: :grin:
LOL :thumb:

Though this thread should be very active again, since the TD will not be on the list anymore...
I vote for GME-20 or other not *that* wxpensive to build EQ and definately PRR's vari-mu (maybe a little bit pimped up to +4dB...) ! Maybe Kent gives permission for his layout, but maybe a new version would be even better (well, 'pimped' like fabio is used to do on everything, ya know - 'options!')...

Kind regards

Martin
