[Jukebox-list] LPC1 amplifier rebuild.Do the mylars need replacing.

[Jjmscf at aol.com]

I finally got the LPC1 running and selecting after near full  
dissasembly,unsticking stuck parts,cleaning and relubing.The mech works great  after some 
contact setting and some needed readjusting.Thanks to Ron's tip in  his book on 
the adjustment of the RSR-LSR and RR contacts I cured the  problem of the arm 
not moving over before the record came back up when I tried  to play both sides 
of a record.I had to clean the mute relay contacts in the amp  like Jackie 
did to get it to reject and mute reliably.I had 1 cap shorted in the  write in 
circuit which I soldered in the replacement temporarily while I  got all the 
contacts and mech working.Every selection works.Even the coin mech  works. I 
have 0 speed problems with this LPC1 and the mech runs great.Gets  right up to 
speed on 45s every time.I couldn't believe it with all the horror  stories I've 
heard about the speed problems on these.I even took apart the motor  and 
cleaned the shaft and bearings and the little ball.I liberally lubed it with  3 in 
one motor oil.New motor bushings and a new plug underneath.The coupler was  
still in great shape and soft and flexible on mine.I guess one tip to is that  
everything must be as free as possible.The motor,turntable shaft bearings  
,everything.Get that old improper lube out of there and use the 3 in 1 motor oil  
Ron recommends or Seeburg oil if you can get it.Also the autospeed hum is  
gone.
 
So now I have  disconnected everything again to rebuild the  Tormat control 
center,auto speed and amp to replace the old paper and  electrolytic caps.My 
question on the amp is that this amp has mylar caps rather  than paper caps.Do 
they have to be replaced or are they ok because they are  mylar?I already 
bought all the electrolytic and paper caps.The kits are kind  of  pricey.I can get 
the caps cheaper myself.The sound is ok.Nowhere  near as much power and bass 
as my 222.The highs are nice and clear if  the volume is up loud.The highs seem 
kinda muffled at low volume.I tried an  unrebuilt TSA4(couldn't connect the 
muting circuit) and it sounded about the  same.The woofers rattle a bit with 
low bass notes so I'm gonna have to get  replacements or reconing.Then it's time 
to work on cosmetics.
