4K,6K,8K Series / Re: Ultimation Fader Issues & Parts

« Last post by skipburrows on August 06, 2026, 10:58:37 PM »

Hi Skip,

Give me a day or so, as an order of some alternates just arrived. I've got a few to fix and test to see if this replacement works.

Have you replaced the 1ohm current sense resistors?

Anthony.

Hey thanks Anthony..
No I haven’t yet, do you happen to recall the r designator for the resistor?
Appreciate your help…

4K,6K,8K Series / Ultimation Fader Issues & Parts

« Last post by skipburrows on August 04, 2026, 11:19:11 PM »

Hi All,
Ive haven't been servicing an Ultimation Fader in a while and couldn't find this info.
Ive got some creeping faders and I know it's usually TR6 and TR7. Does anyone have a suitable replacement for those and also any other common causes of this fault?

Any info would be sooooo helpful...

Cheers Skip...

Hi Anthony,

You should try to contact Frank Cross (https://forum.sslmixed.com/index.php?action=profile;u=78817)
I was in contact with him a long time ago. He was trying to port the 4100 to a CPLD.

Cheers,

4K,6K,8K Series / Foreman Hart Processor

« Last post by horizonsound on July 30, 2026, 08:23:04 AM »

Hi all

Would anyone who has a Foreman Hart processor running both 3.5" and 8" disks, be able to drop me a message.

The Foreman Hart in question, did not have an onbard 3.5" disk drive controller, so there is a separate card for the 3.5" disk, to the left of the memory card.

I just need to know the card configuration when both a separate 3.5" disk controller, and 8" disk controller card are installed.

Thanks!
Anthony.

Thks Walrus. I'll look into it. So far everything is working, but I don't know for how long.

Maybe try replacing it with a ZTX553 which has a 1A current rating.
Different pinout, but I'm sure it can be fitted.

4K,6K,8K Series / SSL 4K VCA to Monitors is not working.

« Last post by Dave Dicson on July 15, 2026, 06:59:26 PM »

We have 2 SSL 4K G Series large format consoles, that about every 5 - 10 months The VCA to Monitors button just stays on and does nothing on both SSL's when pushed. What is happening is that TR7 (BC212L) transistor on the 21 card is shorting. Anybody have any idea why?. I just replace them until next time, when it happens again. Maybe transistor is not heavy enough for the logic load on these big consoles? Are small SSL 4K console has never had this problem. Thks for your info.

4K,6K,8K Series / Re: Plasma hell! CF82E75, E74 and E73 cards! Please help!

It never goes any higher than 1 segment on any meter.
As the audio signal gets hotter the 1 segment just gets brighter and brighter but never lights any more segments.

If you're only getting one segment it suggests the ramp generator isn't doing it's thing.
To start with I'd switch of the HT (for safety) and start looking at the signals on the Ramp gen card with an oscilloscope.
It's been a few years since I had to diagnose and repair a plasma system, but the Tech info in the service manual is quite good in terms of what you should be seeing and where as far as I remember.
