The DSS are in very good cosmetic condition, like a new one it's incredible.
I've not ever try it but I've a question :
I've 2x 6m Philips cable but no end plugs, should this end plugs obligatory to working? how they are made? :think:

The cosmetic was good but I supose I should replace all capacitors Inside, you think it's a good idea Movieman?

You MUST use an endplug (75 Ohm resistor). It's for the system to know which DSS is the last one in the chain, the signals will be adapted accordingly.

Solderwork, new relays, bridges and elcaps are to be advised of course. Please use A-brand components only!

The circuitboards are sensitive, the kopperlayer can easily come off.

Ok moviman, there is a 75 ohm resistor Inside the cinch or just a strap?

I only use Panasonic/Nichicon/Elna... from Mouser or Radiospares so don't worry I will do my best ;) I've a lot of practice with hard work on DCC900' pcbs services so I'm ready :shifty:
For the relays I've see that Fujitsu (Takamisawa) 36v VB series are discontinued but FTR-F1 series could do the job ? (24v with a 680 Ohm, 1%, 1 Watt resistor on 9280 place) ?
I've Finder relays too at my job so I think I will find a good one :whistle:

The plug has a 75 Ohm resistor build-in between signal and GND yes.

The FTR-series are a good replacement, they just have a different coilvoltage. A 0,6W resistor would probably do the job as well but I'd rather go on the safe side.

I always buy Vishay BC elcaps for the DSS, for the powercaps Nichicon LGY, for the bridges Diotec GBI25D (they fit nicely).

My DSS look factory new as well. :dance:

Hello !
after long time without new hifi gear, this week-end a friend delivery and sell me for a little price a pair of DSS 940 :dance:
Unfortunatly, the are not in very good state like my DSS 930 but it's time for a good winter restoration :D
Very dirty, dead bass speaker foam, vinyl under speaker cabinet destroy, and front protection plugs broken for an half :?
Yesterday i've clean it all and dismantle the two speakers to fix the first problem: the dead woofer foam
I'm in France and I've find in NL a website :

https://www.repairyourspeakers.com/inde ... 88&lang=nl

Is it the only seller who have the good foam for Philips AD 70623/W8 speaker or have you another good address ?
Thank you and picts will come ;)

These surround are good and fit perfectly. The Photo of the repaired woofer is actualy of one of mine repaired woofers.
You've done a good job cleaning the 940' cabinet, woofer and electronics.
Be sure to solder both cinch busses again too
"Hoezo nu wel genoeg? D'r is toch nog plek!" jaja, waar dan? "Ha! d'r kan nog wat in de auto!"

Thank you Remi,
I will order this ones to repair the woofer.
I've made a lot of solder repair after the cleaning of pcb's but I've not test the electronics yet (perhaps relais changes, etc...)
I repair the woofer first ;)
I will probably made a new vinyl wrapping of the cabinets if I find the good material to do that because the botom was very ugly.
