    Paradigm 11se mk3

    Recently bought a pair of Paradigm 11se mk3. Could not be happier with my purchase. As a curiousity though, would anyone here have a crossover schematic or a cap list?

    Project: Pioneer SX-750

    Was talking with a co-worked who has taken possession of a family member's collection of vinyl and is looking for stereo setup. Was considering offering the SX-850 that I just finished, then I spied a 'rough' SX-750 for sale. My preference is SX-850 and up... but the SX-750 that I rebuilt a...

    Restoration of a filthy (and hacked) Luxman L1

    I'm about to restore a Luxman L1 that I got recently. The L1 was the simplest of the "Studio Standard Series" from Luxman in 1979. I love this amp because, while being simpler than the rest of the line, it is surprisingly slim for the time, and (when in good condition) punches way above its...

    Project: Pioneer SX-3800

    Few weeks back, I stumbled on a local Fluoroscan. It was non-working and was concerned that the outputs many have been blown (from what I read). Though not the top of the heap SX-3900, the SX-3800 boasts 60 WPC (not too shabby). Here is how she arrived. It would not pass the DBT... so here...

    Is it necessary to adjust the bias after replacing filter caps?

    I'm currently rocking a Pioneer SX-50, which works and sounds great. It's almost 40 years old, and I'm wanting to replace the filter caps just for reliability reasons. I have a pair of Nichicon's coming in next week, and I've heard about AK'ers adjusting their bias after a recap. Should I be...

    Restoration of Acoustic Research AR3 Speakers

    So I fairly recently obtained a pair of AR3 speakers that were in pretty bad shape and, with the generous support of members on this forum and a few other sources (more on that later) I managed to restore them to what I feel is a good representation of their former glory. I wanted to share my...

    Allied 333/Pioneer sx34 - minimum work required

    Hi, I just scored an Allied 333 (for $5!! + 1 hour drive). It's my 1st tube amp. I have some experience with restoration/recap of solid state units but tubes are new to me and they seem to be coming with totally different set of problems to resolve. I was very excited to see that my Allied 333...

    Replacing Sherwood power supply caps with standard radial instead of Snap-In - Bad idea?

    Hi All, First time poster, long time lurker. I believe the title says it all - I'm having some trouble with my Sherwood S7100 with a scratchy volume pot that is VERY loud on power up. I ordered new PSU caps, but foolishly ordered radial leads instead of snap-ins - the amplifier just has wires...

    I recently hired jlovda to recap and update my McIntosh C33 preamp, which is a complex beast with all kinds of boards and subsystems. John did a beautiful job both visually (clean work) and aurally — the preamp is now even more quiet, transparent, reliable in every way. John also worked...

    Luxman L-3 recapping/restoration

    I recently bought a Luxman L-3 for a good price, without knowing anything else from the seller other than “untested, but it powers up”. Good enough for me! For a cheap price, it was worth the risk of getting an irrecoverable amp. The amp looked dirty but well kept, so I went for it. This will be...
