Kev's "Cobble Together a Good 3000 PL Preamp" thread...

I think that was Jer's line Joe..

The footprint looks like 2FormC and looks like room to dead bug substitutes to the board with more reliable relays.

That's what I was thinking, but I thought the switch footprint was different? Checking it out again...

I see no Cobbling what so ever Jer !!!!! No rush man.... No rush !

Tack the standard relays on their side Jer and neatly wire over to the existing padstacks on the PCB. Add a dropping resistor to get from your new 15V to the 12V relay coil

There you go, Joe! Do you see one on mouser I can check out?

How's these?

These here seem pretty good. Yeah I can deadbug them easy!

See if you can find a gold crosspoint contact relay for this application Jer.

Something like this maybe Jer

653-G5V-2-DC12

There are 200 ish in this same low voltage, low current category Jer. The Omron is not a bad choice.

I was a cap soldering fool today. Recap done, and both buffer and tone amps replaced with killer bugs.. Joe I went with 16 volts. Seems to work good!



The bugs.. they are bees.... making sweet SWEET honey right now as I'm listening. Sharp.. yet quiet... Kev I think we got a winner.. so yours is next (soon as I get over this nasty chest crud I have... UGH)

Glad you came to a good compromise Jer.

No pics of the dead bug?? Ugly ain't they??

 

[jbeckva]

Saving the pics for Kev's redo.

 

[laatsch55]

They are nice lookin pre's.. Kaleb has one. I had 5 at one time...

 

[jbeckva]

Sounding FANTASTIC!!

Here's the datasheet for the bugs used...

[jbeckva]

Relay stash.. what stash???

All the yellow guys are new replacements.. geesh LOL

Waveform, nice and clean... but now it's time for the RECAP.. we will make him stronger, faster, able to kick a kangaroo's ass.

 

[jbeckva]

I am LISTENING... and...

INCREDIBLE!!! What a difference. Dave to answer your question on what was the best pre I heard.. THIS one.. and the other 3000 just redone!

Dayum... Well Kev.. you're in for it now, buddy!!! Get that system together and beeamazed.. hehe..
