MR. KELLER:
DON'T HAVE PRINT ON BC210, I DO HAVE SEVERAL NOTES
ON REPAIRS,
MAYBE THEY WILL HELP.
ON PIN 6 OF IC5 YOU NEED 8.6V, IF ABSENT-LOOK AT
R103, COULD BE
BURNT OR DESTROYED. R103 2.2 OHMS IF EITHER CONDITION IS FOUND CHANGE
C97 220uf 10v use 16v or HIGHER. SOME CASES 1C5 WAS BAD ALSO.
ON PIN 5 OF IC5 CHECK FOR 4.19V, IF VOLT. IS OFF
CHANGE C98 (IT IS NEXT TO T1--TF-317 THE CAP. WILL VARY IN VALUE FROM
22uf TO 47uf@ 25v,
REPLACE WITH 33uf @ 50v.
iIF VOLTAGE IS STILL OFF T1 MAY BE BAD. ONE SIDE GOES TO GROUND, CHECK
FOR
CONTINUTY OF THE WINDING. YOU MAY SEE IT BROKEN AT THE CONNECTIONS.
EITHER REPAIR OR REPLACE.
NORMALY REPLACING C98 WILL REPAIR 75% OF THE UNITS.
NOTE: SOME MODELS HAD 4.55v ON PIN 5 OF IC5. IF
THIS IS YOUR UNIT
YOU WILL FIND CAP. C88, REPLACE. IT IS LOCATED NEXT TO T5 (TC-831-01). IT
WILL
VARY FROM 22-47uf @25v, CHANGE TO 47uf @ 50v. RECHECK FOR YOUR 4.55v ON
PIN5
OF IC5. IF OFF T5 MAY BE OPEN . C88's NEGATIVE SIDE GOES TO GROUND SIDE
OF T5.
IF T5 IS OPEN REPAIR OR REPLACE. C88 NORMALY IS THE BAD PART AGAIN.
THANKS FOR
YOUR TIME
