Redline 60 Type 6503 Refurbish?

21 replies

So Duane (Note 1) comes by today with a pair of Redlines.  I've been hoping to find a pair of 60.2's to refurbish and put in the garage with a Frankensystem (Note 2) until I find a stacking system to match them with (Note 3).  When he opened the trunk (Note 4) I thought maybe I'd get lucky, but alas, they were RL 60's Type 6503.

I explained to Duane they probably weren't worth the $50 he paid for them because of the foam rot problem with the ABR I read so much about on the old site (Note 5).  I picked one up and shook it to show Duane, but wait a minute, no rattling sound.

I picked up the other, shook it, no rattling sound again!  What do we have here?  A fixed pair?  But which fix?

A home brew refoam?  A refoam by a professional, perhaps even Martin himself?  A conversion to the bass reflex?  Mike Cason's conversion with passive radiators?

Below is what one of the fronts looks like.  They are dusty and need new cloth.  But no scratches or dents.  No accessories either, except for the small metal "lean on the floor" attachment.

 

Note 1.  Duane works for me and makes just as much money on the side buying and selling at flea markets and on Ebay.  I've bought about a thousand records from him in the last year for less than $200.

Note 2.  The Frankensystem is currently NAD 7175PE (love this receiver), BG RX2 w/ MMC4, BC3300, Beovox S40, and some very cheap Magnavox DVD player.  Used to have Beosystem 1900 in there with second pair of M70s, but the M70s were removed for a Top Secret Project.

Note 3.  Probably a 5500.

Note 4.  "Trunk" = "boot" 😎

Note 5.  I remember one thread - think it was Leslie's - where Gunther complimented the refurbisher on the fabric by slamming my psychedelic M70 grills/frets.  πŸ˜Ž once again.

And the back.  Apart from being dirty, they look OK.  Better than almost all my speakers when I got them, except maybe my S45-2s.

 

And finally, the inside.

Which fix?  NONE!  Someone must have opened them up, removed the steel plate of the old ABR, and closed them back up!  Without bothering to remove all the rotted foam!

So - do I tell Duane, "Thanks, but no thanks."  Or do I have a go a refurbishing these?

 

1, Duane ask for an increase of your salary,

2. Secret Project, pics or it didn't happen

3. Love my 5000 stack

4 Trunk/Boot, place to store golf bag and remains from last years picnic.

5. I think it was about my redline Beovox 3702, and he didn't like mine either

😁😁, nice to see you got something to do again.

Oh man, my hands are itching when I see this. It looks like the RL60's has this ABR and the RL60.2 not? I did these a while ago and posted a thread on the old forum.

Winter is coming, so why not refurbish them, with the help from Leslie nothing can go wrong, and you will need them for the 5500 pizza boxes.

I can find a pair of ABR plates in the dungeons if you need but I suppose postage would be a bit steep.

Beside Rich's obvious kick in my a$$ 😎

This is an insight of some RL60's I've got.

There must have been a retrofit kit to replace the ABR with those tube plates. I think Leslie even had the number...

EDIT 1: The 2 RL60 plastic stripes are missing

EDIT2: Still not a fan of those grills πŸ˜•

Yes there was. I believe that from all the cures to the broken ABRs, that would be easiest and cheapest to remanufacture. I guess all you would need is the location of the reflex hole and the lenght & cross-sectional area of the tube, and it would be close enough to sound reasonable?

I am Duane's boss at a metal fabrication shop, and unfortunately, I have no say whatsoever in what he is paid.  I wasn't really making a comment on how LITTLE he makes working for me, but rather how MUCH he makes selling things on Ebay.  He once bought a pair of Magneplanars for $100 at an estate sale and later sold them on Ebay for $800.  That's a typical day's work for Duane with his "side" job.

The Secret Project is still in the planning stages and so there are no pics.  Yet.

A B&O stack has been my "dream system" since about 1990 when I saw an MCP in operation at Hi-Fi Buys in Ann Arbor, Michigan.

Well, I have been keeping busy.  Lots of new records, built a new rack for the Beosystem 2400, built a pair of speakers that utilize some modified Fostex full range drivers, etc.  Just stuff that doesn't interest the broader community here.
