Kits needed to build an LP-PRE?
#1
Kevin.

Greetings. I have a question for you and/or the Community.

I would like to build a complete LP-PRE in a 1U or 2U rack unit.

As I see it I need the following kits:

PSU-PRE
LP-PRE
BFX
ERK
PSA
QS-LV
And a chassis kit.

Am I missing anything to complete this?

Can you tell me whereabouts I can secure the pieces/parts to mount cards in vertical orientation in the Hammond chassis?

Many thanks,

Hi Jim

Always best to go with a larger chassis for more air for the components, and for more space for your hands to work in.

PSA is actually PSW, Panel Switch.

PU-PRE-24 is heavily filtered and BFX and LP-PRE follow Galactic Grounding principles, so QS-LV is not really needed unless it appeals to you for "ultimate quieting".

If you use the 2U chassis, then mounting of the boards is greatly simplified, using a nut or two as spacers on each bolt.

Have fun

Thank you. PSA just slips off the fingers too much these days what with abbreviations all the rage...

2U works for me. I tried a preliminary layout, PSU off to the side and back, LP along the front panel. It looks like I could get away with an 8" chassis depth given the size of the PCBs.

I could see a use for the remaining space to infill a power section later, but a separate power amp has been the plan all along.

I'm gearing up now to point to point wire a Soma84 from TUT5 in an Epiphone Valve Jr. shell. I expect it to be quite a sleeper. Tongue
