Default HMV ls7

This extension speaker came up a lot better than I was expecting.
The cloth on the front & back was absolutely rotten & beyond any help but I did find something similar in one of our local charity shops.
The unit is quite well made with the speaker mounted on a removeable baffle board, all the mounting screws go into captive nuts set into the wood including the back panel.
The back panel was held on with two wood screws, I changed the screws for modern ones for the time being until I can find some age related parts.
The speaker still had it's original dust cloth around it but that was disintegrating too, my better half volunteered to make a new one, result!
Removal of the speaker showed a cone & suspension in very good overall condition, no rubbing on the center pole either.
Voice coil reads around the 3-4 ohm mark.
At some point in time the matching transformer had been removed.
I haven't completed a project for quite a while so this was a nice gentle re-introduction!
I've always wanted a cathedral shaped woody in my collection but the radios are a bit beyond my pocket money!
This was a good compromise.
Despite much hunting round t'interweb I can't come up with even so much as an advert for it.
It is, at the moment, hooked up to my Defiant MSH902, sounds good too.

I assume you repolished the cabinet, how did you do it?

McMurdo,
The original varnish had gone black with age as is the case with something of this age.
That was stripped off using Acetone & 0000 wire wool, a mucky smelly task.
As the old varnish liquifies it tends to fill the grain of the veneer nicely.
Let everything dry out for a few days then a light rub over with clean wire wool.
Two coats of Danish Oil leaving 48 hours between coats & voila, job done.
My cabinet finishing skills are, at best, amateur beginner but this one turned out ok.

Just for comparison sake, here's the thread I posted when I first got this item home, the phone camera makes the finish look far lighter than it was!

A fine-looking job!

I have re-finished several sets using Danish Oil and I like the finish it produces, plus it’s relatively easy to apply and gives good results. One tip I tried and which gave an even higher gloss finish is, when fully hard (2-3 weeks) to polish the surface with something like Liberon Burnishing Cream.
