Hi Guys
$400 for a chassis - maybe if you want it to be pretty and look exactly like the LA-2A. You can still make it pretty for a lot less, using a chassis from Aliexpress - easily cut the cost in half or more. You can also get very nice meters there, too, and the large Alps stepped pots.
Hammond's 140UEX has performance to match any Jensen or Lundahl. It is 10k:10k with no CTs, which makes the winding simpler and it has the best performance in the entire series. It can also handle gigantic signals. I would suggest using one for the output and probably another for the input.
You can go simpler with the input and output and be transformerless, especially considering these are not technically part of the "compression" circuit.
The tricky expensive piece is the EL cell. I have one if you want to email me for a price. Sit down when you receive the reply
Like I said above, everything other than the EL element is bog standard.
For the transformerless compressor, just use a dual triode for both ssections and try it. It is not that hard of an effect, so you may not want to invest too much into it. But, yes, you can sub a real dual-diode.
Have fun
