After all, return can be made from us.....who wouldnt spend a little extra to have the actual Pass parts?

Be realistic, Nelson is not in parts selling business. Listen, there are already Semi South available power jFets to be purchased. We are not even remotely "there" yet, in terms of use of available and existing Power jFets. Not to many schematics, not too many experiences shared, not too many mods... So why hoping for unobtainable, when available ones are not explored that much. The ones that I tried sound exceptional. Try them first.
 
:rofl:

there is always Holly Grail in audio DIY ........

and you're right - that there is simply no meaning trying to walk in same rhythm with Papa , just because we are at least 10 steps behind ;

should we just ask - where are all those LU jfets , bought by Greedy Boyz ?

seems that just few dozens are singing ......

and after these - we had depletion mosfets , current SS Jfets ........ and just then Papafets .

there is still long way ....... to be worth of asking for possibility of buying these most current ones

:clown:
 
Hi

While looking at BAF photos, there was something that caught my attention: BOB, actually its backside... 😀

I noticed something that looks like a simple first order passive crossover, with just a coil and a cap. Wouldn't be surprised to find out it's a simple series one... 😱

100 uF high pass , 12 mH low pass

Also, I put 0.25 mH in series with the Lowther PM6C
to trim the top.

😎
 
Vladimir took a nice picture:

Is that Big Open Baffle?

How big are the wings? I'm assuming BOB is the one that had the Seas prototype in it and not the Feastrex. Sorry I didn't make it this year but am glad a good time was seemingly had by all.

Thank you,

Chris

BOB is the Big Open Baffle, what started out to be a nice
little article that has turned into War and Peace.

At BAF the SEAS driver had its own baffle 24"w x 72"h
with 15" wings.

Here's some response pics on it. Note that the first three
do not include the high frequency range.

Darn you, why did you say that, i'd park my sleeping bag at the dealer's front door for a (free, i hope) test drive in Pass automotivated sound wheels.
(with heatsink-hot Master Carred plastic and a borrowed furr coat to have a chance to pass the screening, of course, should be obvious)

Even in a Fuh..., Fuhh..., Oh, forgetaboudit. :headbash:
