    As mentioned in my post, the Stanton used permanent magnets to float the turntable, using a spindle with a hardened needle point to keep it centered. Turning was achieved by a metal one inch or so protrusion about six inches in diameter that was powered by a 32 pole (as I recall) electromagnet with sequenced charges. Price was 98.00 with 681EEE.

    Do you think you can find this turntable and donate it to me? 😇

  2. The problem with this turntable is that it would not be very practical.  Once the first side of the record is finished playing, you have to turn off the turntable, wait for the feet to rise and carry out the start-up procedure all over again to play the second side of the record.  It is very time-consuming and hinders the listening experience immensely.  In my opinion, it is not worth the price and the listening experience!

    So, I've admitted above, I don't smoke, drink, exceed speed limit, stop, look & listen at all railroad tracks, stop at signs (even yield) ...

     

    I don't smoke anymore (can't stand the smell).  But I still drink, speed, don't yield and sometime pass stop sign.  I am not aggressive but It is just a part of life.

  4. I quit smoking almost 25 years ago.  I used to smoke about 2.5 to 3 packs a day.  My doctor told me I still have trace amount of nicotine in my body.

    this is magnequest

    That is interesting.  The schematic Marvel provided is Electra Print but the technician replaced R10 and R13 with the resistors from Manequest parts list.

     

    erik2A3 confirmed that my Moondogs indeed have Electra Print OPTs.  I trust the technician but I am wondering why he replaced R10 and R13 from Manaquest parts list?

     

    My Moondogs seemed to work great and sonically better then before.

    No need to leave amp "ON" all the time, if that is what you were doing previously. !!  Its hard on tubes, etc. 

     

    Actually, as far as I can remember, I have only left the amps on twice (without turning them off) for a periods of maybe two to three weeks each time.

    The technician told me that according to the schematic, two resistors were wrong.  R10 was suppose to be 2K not 1K and R13 was suppose to be 1.8K not 1K.

     

    I forgot to mention that he replaced the R10 and R13 resistors since they have the wrong values.  He also replace all of the 10uF/400V caps with 10uF/630V caps.  As of today, the amps are almost dead quiet.  The sonics did not change but got better.

  7. I finally got my Moondogs back.  They were burned in for about 3 days.

     

    All of the caps have been replaced.  All of the sockets and pin holders have been tighten.  The technician told me that according to the schematic, two resistors were wrong.  R10 was suppose to be 2K not 1K and R13 was suppose to be 1.8K not 1K.  Other then that they sound incredible!  The longer they are burned in, the better they get.  Sonically, they sound better then before.  They cost me a total of $450 for parts and labors.  I am extremely happy with the sound.

     

    Here are photos of both amps.

    Open E on a double bass or electric bass is about 41 Hz.  Open B on a 5-string bass is about 32 Hz.  Kick drums run about 50 -100 and companies are similar.  So for music, a Klipschorn has all you need. 

     

    So I should be able to play 1812 Overture on Klipschorns with no problem.  Any problem playing it with my flea amps (2A3 Moondogs)?
