Altec A7 Refurbishing

[vottnut]

I am getting closer to finishing up my Altec A7 refurbish. This has been a 2 year project (on and off, mostly off). I have uploaded many photos to share my progress. This pair of A7 was strip of its paint, re-braced both the lower woofer horn panel and bottom panels with 1 x 3 lumber. Two coats of primer follow by two coats of grey #5. Finish off with new decals and stencils for the front panel. Both speakers are dampen with Ultra Touch Blue Denim type insulation. I have some questions for my fellow Lansing enthuses. Should I do anything to the cross over units. They seem to be fairly clean. I hear folks talk about upgrading or changing the capacitors. Is it worth the work? If so what are the cost? Where so I look? Parts-Express maybe, any part number? I also hear talk about changing the wire size and adding a felt pad on the inside cover of the HF driver. What should the ohm reading be for the HF and LF drivers? Where can I get a copy of the cross over specs?

Many thanks,

Hi,

I think the dustcap of the lefthanded woofer needs to be replaced . Besides that, excellent work. They look like new now!

Best regards!

Nice Job!

Those look good, and the sound is really nice and effortless, with very little power.
