Peter, I defer to other members on this, but I doubt you're going to find a better fitting driver. The vast majority of 8" drivers are about 225mm diameter. I'll let you in to a secret way I've handled this problem in the past - the purists among us will probably shoot me. You're short of about radius 2mm around the circle. Mark

I've restored my 4 S45's (6302), and having had them since almost new (demo's from a B&O dealer in 1977), and they have been well taken care of. If I had to replace them, I would be very careful when buying second-hand drivers, and I wouldn't pay very much for them, unless they were from someone I could trust, like a fellow BeoWorld

The Monacors are Oriental, marketed by a German company. The Peerless are European designed, but no idea where they're made. I'd prefer the Peerless, if they fit.

Martin Olsen may have spare drivers - Martin, are you here? I understand that the voice coils are burnt, so you definitely need new drivers. If all else fails, check these 8" drivers Peerless 830869 HDS-205 Nomex, and the Monacor SPH-200KE. EDIT - Actually the SLS 830667 looks like a better fit. Before buying, check the dimensions really well,

Hi Colin On the attached picture, you can see my rebuilt IF Can, on my restored BM1400. On the left side, about 2/3 way up, you can see a new 10uF 50V capacitor, which replaces the usually faulty tantalum capacitor. A Panasonic EB, or Nichicon HE capacitor is a perfect and very reliable substitute. My BM1400 also suffered the plastic tuning wheel decomposition

I have repaired many broken plastic parts of vintage equipment. by using slow-set epoxy (much stronger then the fast-set), and layering overlaps on the broken part's cleaned sides, with 2 layers of thin cotton fibre for strength. IE Plastic - epoxy - fibre - epoxy - fibre - epoxy. It builds up the thickness, but it is very strong! Menahem

These units are well known for capacitor problems, and member Martin Olsen (Dillen) has capacitor kits if you're good with a soldering iron. Send him a PM. Menahem

Hi Chartz, To check if an electrolytic capacitor is OK, the primary and most reliable method is ESR (Equivalent Series Resistance), not Capacitance. 99.9% (this is my very subjective number here ;-) of defective electrolytics still show acceptable capacitance, but if you were to check them again with an ESR meter, you'd confirm that they are all

Mike, Firstly, welcome to BeoWorld! To deal with your problem, understand that these are not quick-fix units. But they were built to last a lifetime, so certainly worth restoring. Take a look at one of the posts I've written on this model - http://forum.beoworld.org:80/forums/t/12646.aspx More specifically, understand that transistors do not just

The fact that you're concerned and want to correct it, means we'll make a tech out of you yet! Definitely start checking resistors, without a doubt. On some of them you may have to desolder a leg to get the actual reading. Anything more than 10% deviation (and I would aim for 5% max) is definitely cause for replacement. Use metal or carbon film
