    Pilot 4000 FM receiver ???

    Does anyone have information or opinions on a Pilot 4000 FM receiver? It's a free acquisition, but a complete rebuild would be necessary. I'm looking for information on it to determine if such an endeavor would be worthwhile, but I'm coming up with nothing. There's a big power tranny and...

    Russian 6N2P-EV for 12AX7 ?

    I'm taking the plunge on Sergey's 6P3S-E tubes to use on my Dynaco ST-70, and since I'm having them shipped all the way from Russia I've been thinking of having him include these $2 6N2P-EV tubes for my PAS 2 preamp. Has anyone had experience with these in place of 12ax7 tubes? FWIW, I'm...

    EPI M-100 speaker repair

    Got a pair of EPI 100's (early examples, without tweeter control), and one of the dust caps on the 8" woofer has been poked thru. The cap measures 1 5/8", and found speakerworks.com has generic paper replacements for $2.50 each. The surrounds seem fine, but I plan on replacing the 4.7...

    Grundig garage sale find - $3

    Stopped at a sale yesterday, and among the junk was this Grundig receiver (Model RTV 320 U) with matching speakers - nice sounding unit for $3. The plastic front plate was so cloudy I could barely make out the numbers. And the gold trim was sticky and flaky in spots (same with the knobs)...

    Dynaco PAS 2 tone control bypass

    So I upgrade the power supply in my PAS 2 preamp somewhat successfully, and decided to move on to the next step: bypasssing the tone controls. I initially didn't think this mod was for me. I listen to a variety of music, and sometimes turned up the treble (and to a lesser extent, the...

    Questionable 5ar4 tube - is it a Mullard?

    I got this rectifier tube a while back, and the guy claimed it was an old Mullard 5ar4. It was cheap enough, so I bought it. However, the print is wiped off the glass (save for a hand-written marker on the very top saying this is "EX" - I'd like to think that means it tested Excellent)...

    Dynaco PAS 2 & ST-70 suggestions

    Just got this pair, and I'm enjoying them immensely (thanks REXEVERYTHING). But a couple of questions: (1) Why does everyone bypass the tone controls on the PAS 2 ? I listen to a wide variety of music and find that I'm always changing the treble and bass controls. Don't think I'd...

    Another cork mat convert

    Found some cork today, so I cut a 12" circle out of it. It's very thin, measuring out to a bit over 1 mm. It was rolled up in storage, and still curled when sitting on the turntable. So I decided to put on some weight to smooth things out - in the form of the original Denon rubber mat and...

    Bypass Capacitors

    I'm finally replacing my power supply capacitors, and have a question regarding the bypass caps. They are contained in a separate can mounted above the chassis, and it's marked 50-50, 50-50, CAN COM NEG. (I assume this means two caps at 50uF / 50V each). The schematic shows 25uF 25V for each...

    Acoustiflex suggestions?

    1970's "Acoustiflex" - SS amp/receiver.. any mod suggestions? Here's something I'll bet nobody has ever seen - and I say that because I can't find a single bit of information concerning this brand. Acoustiflex was a Detroit area company in the 1970's, that much I know. And judging by the...

    Sony TA-1130 speaker protection relay - or lack thereof!!

    Acquired this nice-looking Sony, and was really impressed for a while...but after a few weeks there seemed to be a problem with the speaker protection relay: the amp required turning up the volume knob really high to get any sound. After doing that, the channels were not equal in their output...

    Sun Ra Delmark LP reissues - any opinions?

    I have been considering the purchase of Sun Ra's "Sun Song" LP by Delmark for a while now... but having been seriously disappointed with some jazz LP reissues' (the Fantasy label, for example) I wondered if anyone's heard this record and what they thought of the pressing quality. I have...

    Resistor replacement suggestions

    I finally got to work on this little push-pull McGee amp, beginning with a recap. I'm using 716 Orange Drops and the five that have been completed have drastically improved the sound. I plan to replace all, but I'm doing it in stages so I can hear the difference along the way. But in...

    Sony TA-1130 L/R channel outputs differ

    Have been enjoying this for about 6 months, but lately it's been exhibiting some problems. The output of the left channel is lower than that of the right. Sometimes it cuts out entirely, and I turn the balance knob all the way to the left and crank the volume up - that gets the signal back...

    buzzy first project

    I have recently purchased this old McGee Imperial 30 mono amp that has a buzz at lower volumes which goes away when the treble is turned down. The buzz does not increase when the volume is turned up, so at higher listening levels it's tolerable... but I'd like to fix it. Does this sound...
