Thought about taking the case of my lamp ccs, but can never bring myself to do it. It has its place.

Love to hear this combination. I'm also currently connecting L'amp to JBL.

Very nice room!

Can't compare performance of new amplifier without good old one.
How many big Inductors Vfet mono blocks on this planet ?
Last two

Dear all,

Due to a recent experiment I declare that I will mod my L'Amp-without-lamp to feature a cascoded output.

Cheers,
M.

You should be able to remove the casters then.

With that inductor loaded amp using the 2sj28 or a 2sk180 for that mater what would the output impedance be. I have a pair of coils just like that and would like to build it but want to drive a passive xover with it. So the question arises whether I need a voltage source xover or a current source xover ?

Can I do the same with L'amp 2SK180 ?

Thanks in advance
Imho yes You can do the same
My L'Amp 193V is with input transformer but 1:1 configuration.
Maybe i can try make with him passive gain stage in the future
