    Technics SA-700 Receiver

    Yeah, six speakers, the main speakers (2EPI's each channel) wired in series, and the other two EPI's (one per channel) into remote section. I'm sure if there was a problem, something would have happened , since it was on for almost 2 hours . The room temp was 82. I will take it easy when I...

    Isotap Settings

    I recently purchased a RCA WP 26A Isotap...I have a 1962 Knight Tuner that requires 110-120v....My tech told me to set it at 125 v tap....I think he is wrong. should it be at 120 or 115 tap? Pretty sure he gave me wrong info. Thanks in advance for your replys/suggestions.

    Knight 755 Amplifier

    My Knight KN 755 amp, has lost the left channel, all except some extreme distortion if you crank up the volume all the way....I swapped all tubes, with no results....checked all the critical caps/resistors and loose connections, and found no visible problems, did the 9V battery test to check the...

    Tool for wrapping two wires together,then solder

    Hi Guys...I read on a earlier thread, about a special tool, say when I cut off a resistor, and leave the existing wire, so all I have to do is connect new resistor/cap, and solder the two wires wrapped together? so much easier than trying to pull out old wire soldered in with 2 or more in...

    12au7a

    Yeah, that is what they say.....but, just in case, I wanted some back ups...that RCA au7 has been in there 6 years @ 20 hours per week...so, has lots of hours on it ....neon stereo indicator light still works(that is another story for another time)

    Thanks, Guy....I appreciate that....I found another site that sells the RCA 12AU7A.....so, ordered one of them also.....Right now, I have one RCA, and A CONN, installed, and both work fine, but, wanted backups as the two in there are getting lots of hours on them, otherwise, for a 50 year old...

    12au7a

    I ordered a 12AU7A tube, and when the order arrived it was a 5963....I did the research , and guess it is same as 12AU7A, so my question is: Can I use this in my FM Tuner, without damaging it? I know this is probably a dumb question, but, want to be on the safe side....thanks for any replys....

    The unique sound of FM.

    Yeah......Most FM's now hire engineers that know nothing about sound, signals are overmodulated, final product is greatly compressed, thus, not the great sound fm once had....not saying this about all fm's, just for example "Clear Channel" not to mention, no matter what format...you constantly...

    The unique sound of FM.

    Back in the late '70's, the am station where I was on air dj (worc, worcester, ma) tryed the Peak Modulation, to the point we were the loudest, but, all distorted , and what audiance we managed to have (with increasing competition from fm) was lost....This was a brainstorm of the Station...

    The unique sound of FM.

    am radio sounded good in it's day, when the station used analog transmitters i.e. TUBES , not transistors......and before the am recievers were cheapened.......but, the first time I heard FM, I could not believe my ears....what a difference, crystal clear, full dimensional sound, later...

    Majic Tuning Eye adjustment

    DO YOU THINK IT COULD BE THE TUBE GONE BAD? Basically it is almost wide open with the full exclamation point, but, does close a bit, on a strong signal, but not all the way....maybe 1/4 the way......Tried swapping out the resistor that carries the voltage, and nothing worked, stayed the same...
