    Recap Technics SB-A13 speakers

    Hi all, my Technics SB-A13 3-way speakers are acting strange, at lower volumes the tweeter won't work, unless I increase the volume. Once, increased the volume and lowered back, they work fine. I suspect the capacitors are dying...any thoughts? The capacitors that I observed, have unusual...

    New restore project, Marantz 2220 (the sequel)

    So I was watching the local Craigslist for my next 'project'. A non-working Marantz 2220 came up. I contacted the seller about what was broken and he gave me a link to AudioKarma thread. This unit has been here before but was unsuccessful. I will document the progress in this thread, and...

    2230's C753

    I've read quite a bit in various threads about this and in my recap I've replaced the item with a 10uF, in accordance with the received wisdom of AK. Being now in the final stages of the refurbishment, the sound seems good to my ear so no direct complains about the choice. However, can't escape...

    Pioneer A-80 Restoration - Recap & General Notes

    I recently picked up a Pioneer A-80 on the cheap. It had a non-working channel with bad outputs and other various issues in that channel. After quite a bit of troubleshooting it's in running condition and received a full recap. Seeing as there's not much info on this receiver I figured I could...

    Question for anyone who has recapped/repaired a Concept 11.0 Receiver

    Hi all, I recently got my hands on a decently clean Concept 11.0 Receiver, and I'm looking to give it a little TLC on the internals. As has been published in this forum and elsewhere, the inside of the receiver chassis is pretty nicely organized, and all of the boards are connectorized and...

    Dynaco A25 woofer blown? - Help!

    Hey Guys, Made a previous thread about my A25's, the highs being low/muted on one side and planning a recap. Started to get some distortion from the same speaker and didn't investigate it real close, thought the recap would take care of it. Of course it was the woofer though. Recap and deoxit...

    Quickie 1030

    Hey All, got a 1030 the other day, it had a nice wood case, so I picked it up. Did a quick recap and set-up, sounds nice for a very small amp, but a little lacking in the low end. Here's the pics.... Thanks Rich

I find the details in the music and the smoothness amazing, especially in the mid an high band. When I use this amp, it sounds flat and lifeless and extremely boomy / flabby on...

    Rare Teac TN-400 turntable - speed control repair

    I've had a Teac TN-400 Magnefloat turntable since '79 or so. It went into the closet for a speed-control problem after a few years. Dug it out a couple years ago and got it going, sort of, but it still has speed issues. The adjustment knobs are all the way in one direction, but that is not...

    1070 in the House

    Hey all, While I'm waiting for parts on the 2015, I got a 1070 from a school district listed as turns on. Well, it was in very nice shape except for the numbers scratched in the faceplate. Put it on a DBT and it did fine, so I recapped the power supply, power amp, and tone board. What a joy...

    Should I recap? Sansui 5000 sounds dull.

    I read several threads here that say recap does not really bring an advantage to the untrained ear (mine...). But: I git thus beautiful Sansui 5000 and comparing it to Sansui 800, Pioneer SX-6000, Sansui 771, others - it just never even made on my shelves to have some weeks of playing time. It...

    Marantz 1150d questions

Has anyone devised a solution for replacing this and I did not find any rebuilt threads on the 1150d, are there any out...

    Recapping Marantz 2270... can I use non-polarized main filter caps?

    Hi everyone. One of the main power supply filter capacitors of my 2270 was leaking and causing sound issues, so I've decided to replace both of them. It's probably way overdue. So I ordered two Mundorf MLytic 10000uf/63VDC caps (http://www.partsconnexion.com/capacitor_ele_mundorf_plugin.html)...

    Widening modern trimpots or trimmer resistors to fit 7.5mm PCB holes

    I'm replacing the trimpots in a vintage (1970's) receiver and I've ordered standard Bourns trimmer resistors, but the new pots have 5mm lead spacing whereas the old ones have 7mm or 7.5mm, so the PCB has the wider-spaced holes. What is the best way to deal with this cleanly and reliably? 1. I...
