Sorry for the delay in getting back to you. I'm not sure if those are still available. Maybe this post will catch someone's eye that knows. I hope they are as the randelschrauben are very well made.

Best,

Hello all!
I was wondering if anyone knows the specifications (viscosity, etc.) for the ferrofluid Braun used in the mids and tweeters. Alternatively, is there a consensus for the best ferrofluid available today to use as a replacement?

Thank you!
Jon

Greetings all! I've been meaning to post some pictures of the Rändelschraube. Reproduction on the left. Hard to see any differences other than the black finish is more matte than the original. Also the "teeth" are slightly sharper on the new ones. Really great quality reproductions that in...

Sorry I seem to be posting too much. I'm just excited about these 710s! They sound wonderful. So...another question. I know this has been addressed here but I can't seem to find the right German word for that sticky doping compound on the mids and tweeters. There is a thought on another forum that A...

Hardware used for mounting stands:
M5 x 15mm DIN 7984 (I could only find M5 x 16mm long but they work).
M5 metal washer
M5 or 3/16" neoprene washer

Thank you Wilhelm! I will have to repair it properly soon. I believe the wire is still glued to the woofer cone as it's still functioning (there is no loose/detached wire) but the adhesive for the rivets and paper grommets has failed. Here is an example from the hifimuseum site: Braun-L710-Chassis-8...

Hallo! Thank you for the tip Wilhelm. That product isn't available here I don't think but I imagine there is an equivalent. The original sealant seems to be very similar to the rope caulk Mortite product. Update: I replaced the capacitors and was surprised that the original capacitors all measured a...

Hallo Braun community! My unscientific analysis suggests that the sealant was most likely composed of butyl rubber. It was applied very thinly and I can see smear marks in places suggesting it was in semi-liquid state before curing to a putty like consistency. Edit: Nah....it's more like Mortite rop...

Hello all, I was wondering if someone knows the correct size mounting screws for the LF700 stands. I thought it was M5 x 15 based on the document below but they don't seem to thread easily into the back of the 710s. I'm not sure if my 710s ever had the stands mounted as the little plugs on the back ...

I'm only replacing the two electrolytic capacitors which are 50uf 35volts and measure roughly 40mm long x 18mm in diameter. I've chosen to go with Mundorf electrolytics: I ordered both the "raw" and "plain" versions of the 47uf: Mundorf E Cap 47uf / 35VAC-100VDC, MLytic Bi-Polar ...

Hallo! I thought I'd document my progress for others who are neophytes and want to see the step by step process. To gain access to the crossover, the back panel needs to be removed. There are 10 Phillips head screws that must be removed: IMG_1380.JPG To remove the back panel takes some gentle prying...

Hallo Gereon,

Thank you for the link. I really enjoyed reading through that thread.

I'll be sure to document my progress once I start the restoration.

viele Grüße
Jon

Hello! I apologize in advance. I know this question has likely been answered but my searches haven't been successful so far. I'm looking to replace the two electrolytic capacitors in the L710 crossover. Is there a consensus for the best replacement of the two 50 MFD 35V capacitors? I've been researc...
