freshmanco: Fresfman Masterpiece 5F4

Hi,

I am new to the forum and need a little help. I have a Freshman Masterpiece 5F4, but none of the schematic I can find have the same terminals. The layout that I have is as follows.

  AERIAL   GROUND     A-    A+     B-     B+     B+AMP

I have built a battery eliminator K101, but need to know the correct voltages before I attch it to the radio.

I belive they should be.

AREIAL  = ANTENNA

GROUND  = NOT SURE

A-    = -5v

A+   = +5v

B-    = NOT SURE

B+   = +45V

B+AMP  = +90V

 

If some one could verify the voltage and advise as to the others I would be appricative.

Thanks

RC

Aerial = Antenna 

Ground = connect with waterpipe (sometimes not required; try !) 
 

A- and A+ = 5 V DC ( originally 6 V storage battery)
 

B- = 0 V   (internally connected with A+) 

B+ = 45 V (works between 30 and 70V)  

B+Amp = 90 V (do not increase: there is no grid bias!)


Good luck,

KoBi
