[Boatanchors] hEATHKIT SB-220 METER SHUNTS

I need  help to figure out some new meter shunts for an SB-220.,---hate to 
admit.it------

Exact replacement for the original 200uA meters ,which burned up,are almost 
impossibe to get.--but I do have a couple of nicely fitting meters,which 
have a 1mA 1000 Ohms/Volt movement.e.g.,they are not quite as sensitive and 
require different shunts or series resistors----I can use the scales and 
housings from  the old meters  .

If you have a schematic for the SB-220, I am talking about R1 and R2 
shunting the Plate Meter and the resistors that are used for the 
Multimeter,to measure Grid Current,Rel.Pwr,and H.V.. (R6 ,7,8 and R9)

I am sure this has been done by quite a few poeple before and it may even 
have been published b/4 .

Any help for this old guy who got his license more than 60 years ago but 
probably would not pass the test to-day,hi. ??--  If it gets too complicated 
or u need the schematic,pse respond directly.

Tnx Olaf,KF4TP.
