ok links please to better than products..NO FANS..... The Samson is the one I foiund.

Y'all have good time..wish I could come, but it is too expensive a trip from CA for me at this time. Dang.

some of my work on D75s chronicled here:

It's magic 0101010101010011110010010 = 0101010101010011110010010

I think that Samson is the modern day equiv of the D75...if I get desperate I'm going to try one out.

FWIW I found fixing the balanced inputs pin 1 problem very easy on the D75s I hot rodded. To me it looked like it might be a little more difficult on the D45/75A, involving cutting circuit traces/adding wires. The rest of the modifications, re capping, adjusting compensation caps, installing I.C. socket(s) swapping opamp amp chips, seems pretty much the same. Because of the opamps I chose to use LME49710s and 720s I had to replace the low voltage zener regs with actual regulators. The zener regs just did not have the poop to run the LME amps.

@totalcomfort ? you still around?

to be clear...PM you or Cory?

so all this talk about the old D75 had me wondering what is presently available that is similar (NO FANS). I found this: https://samsontech.com/products/studio-tools/power-amps/servo120a/ anybody ever try one of these?

oh chief has your old D75s? You better tell him quick lose the plans for UG Jube cuz there this other guy that's gonna make him build some

@hanksjim1 cool article..thanks. BTW do you want to rid yourself of any of your D75s?

Well it's 2 years later...I'm giving up on this transconductance mod to my D75. I will hopefully be able to return it to normal operation but it will take hours of work. On my last attempt something smoked so I'll have to fix that also. I think it probably is one or several of the small signal transistors. I am fortunate that I only paid about $40 a piece for these.

work order for a UG Jube?......that would take some powerful connections methinks.

@dtel did your friend ever get a round tuit? I would love to take them off his hands if not.

FWIW...the D75 and D45/75A are different animals. D75 came first and has 2 single opamps and 1 dual. The D45/75A have a quad. D75 has balanced XLR input and unbalanced 1/4 phone in. D45/75A is balanced either way. There are other minor differences like a lot of hand wiring in the original D75 that was eliminated by the time D45/75A came along.

@Scott Grammer If you pass on it can you pass contact info to me? I WANT it. I have rebuilt 4 and know exactly what needs to be done. I would like to refurb another one.

@Maximus89 What brand of transformer are you using? And are you going from a balanced output to single ended? Or vice versa? I suspect you are getting some attenuation of higher frequencies because of transformer and/or cabling.

@RickD so you can turn the tweets 90 degrees? I wonder if the polar pattern change would effect what you are experiencing.

Looks like you have posted some items for sale in the intervening years.

Welcome back... I was not around back then and by no means am I a newcomer. Is it still your same username/avatar? Or did you have to get a new one?

https://community.klipsch.com/index.php?/topic/207475-jubilee-numbers/&do=findComment&comment=2759784 And Roy agreed.

don't want to start an argument or debate...you KNOW I'm talking about the 2 way home version that you almost had to know Roy to obtain. Of which there are like 50 pairs world wide. And they're now unobtanium unless one is blessed enough to find someone foolish enough to let them go, maybe because of the owner passing.

At the time it was aptly named, it certainly was the nicest looking (bigger) speaker Klipsch made back then.

So Jubilees are out of realm of possibilities?

Best speaker Klipsch never made.
