Jlh. Plh ?
I got back one of my JLH amps back from the loaner department. I started to do some listening tests comparing it to the PLH. Do they sound the same? Not really. Both sound good, but different. There will be more to add in a week or so after I crank that pot to some more positions.
PLH has 37 volt rail with 68000 uf.,.15ohm, 68000 uf. Bias @ 1.8 amps.

I lisrened to the JLH for an hour or so tonight while putting on the front panel and top of the PLH. It is a very good sounding amp. Good highs and lows and good balance in between.
The difference between the JLh and PLH is the midrange. As the current gain is turned down the PLH midrange gets better. Then you get to a point when the highs and lows drop down. For Mr. Pass this is at the 9 O'clock position. For me it is anywhere between the 6 and 10 O'clock position depending on what I am listening to. Ten for Disturbed (Down with the sickness), Jam are you going to send that disc back soon? Six for Goldfrapp (Are you human).

He took them for a week and says he likes the JLH much better.
Some specifics regarding audible differences between the JLH/PLH would be interesting!

The same one Mr. Pass used.

What is the chasis for? Strangely, my amps work without chasis
The Alephs were lucky enough to be built more than one channel
