pull the tweeter out with sticky tape, or a vacuum cleaner
the foam is easy, copydex glue will be fine.
Good idea to centre the paper part on its coil by inserting slivers of card or plastic before buggering about too much.

The speaker cone should centre itself pretty well just by laying the driver on a flat surface. Copydex isn't really suitable. Most refoaming kits come with suitable glue as some adhesives react with the foam surrounds.

The tweeters can often be disassembled to remove dents but be very careful that the connections are not glued to the magnet. In most cases the whole front comes off by screws or clips.

For your AR , just replace the tweeters or live with it. So many have rotted foam that many spare tweeters are available or even whole speakers with dodgy drivers.

Re:

Does anybody know of a UK based web site that specialise in valve amps?
I have a few and many spare parts, including mains transformers, chokes, output transformers, oil filled caps, etc, that I am considering selling.
Also I have lots of speaker drivers spare, I used to design and build loud speakers for friends and family.

Re:

did a little repair work on my PD-95 today.
picked it up from Glasgow on Friday from being serviced, and all is well, plays perfectly!
but, when opening and closing the drawer it sounded terrible, not silky smooth like it should :facepalm:
so, i took it apart and found a broken tooth (you can just make it out in the top pic) on the tray gear.... :shock:
parts will be unobtainable for this from 1992, but fortunately, the gear is long and only the bottom couple of mm drive the tray cog. so i thought i'd be clever, cut it and spin it through 180 degrees, giving me fresh new teeth to mesh with the tray cog. hot glued it back together, refitted, and the end result is i now have a fully serviced and 100% operational CD player again!

Well after a few years of waiting and being out bid a couple of times, landed my dream cassette deck. Low price and in vgc, a sign of heavy usage is oxide build up on the rubber rollers but these were virtually spotless. . Top of the range back in late 80s, Denon drm 44hx ( i got the 24hx, first in the range with dual capstan mech, as it was a fair bit cheaper and on spesh offer from Billy Vees - are they still going?)

Anyways listening to some tunes, V2 by the vibrators.

Eagle eyed spotters will notice front part of cassette door is missing, done to monitor tape, dual capstan and on one cassette the first roller is pulling too much tape so theres a slowly increasing loop of tape because the second pinch roller aint taking it up. A drop of fine oil on the roller spindles seems to have fixed but not 100% sure (or maybe due to lack of use or old rubber belts) so i will continue monitoring.

Proper retro engineering, none of this mp3 memory chip nonsense.

Take a look at Diyaudio.com, not sure if they are uk based but there is a valve/tube section and very likely to be a trades section.
