|
|
On a LUG modified neck board, Pin 6 is drilled through and some resistors are removed and added. To reuse these same neckboard for an LCP, what needs to be done? Will is still work as is or do I need to reconnect Pin 6 some how?

Why not just buy some spare stock neck boards Gino? Fairly cheap and easy enough to do the necessary cap/resistor mods (says he who had to have someone else do the modding!) so that they are upgraded for better bandwidth etc but still have the stock pin layout.
Might be a lot less hassle than trying to put them back to the original pin design and at least you would have neck boards specific to any tube type you may wish to use? Thats what I would do.

Gino here's the pin diagram provided by tse. Looks like the LCP has no contact on pin 6 at least on the P19LCP09. Did the Marquee ever use a P19LCP07 ?

Paul - I have a special version of Mikron neck boards from MP which I use on my LUGs. When I want MP to tweak something or enhance something further or god forbid repair something, I can use my MPv2 neck boards which also have LUG mods. My third 9500LC Ultra/part machine has LCP's. I was hoping that I could put the spare MPv2 VNBs in there when they aren't needed.

No idea about the 07, but my LCP's are 09, and if the diagram is correct it certainly appears like I can do a direct swap between LUGs and LCP's.

Yes, G2 is on pin 2 for LCP09, but I don't understand Athanasios? LCP09 is found stock on 9500's, so of course unmodded VNB works.
