Dear EII+ authorities,

My EII+ with two, 5 and 1/4" floppy drives (making this anEII+), will power up, but will not boot up a good (containing content) inserted floppy disc.  After power up, the floppy drive lights would alternately flash, but nothing would happen.  Since both drives are the same model number, I switched them and tried again, just to see if there was a glitch.  This time, after power up, all lights on the front panel were flashing and what I believe to be,  "the small round yellow capacitor"on the lower left corner of the left (green), circuit board, started smoking, so I turned power off.  I think this might be a capacitor, not sure. 

I reversed the floppy drives back to original position, but the same thing happened and now the capacitor is burned, but the circuit board still looks OK, hopefully because I powered down so fast.

Could the Power Supply be sending too much voltage to the circuit board, thereby applying too much heat to this, the first in a series of 4, identical, yellow round capacitors (labeled 106 over +25K) ?

Is anyone aware of this problem?  Does anyone know where I can get another one of these capacitors labeled 106 (over) +25K on the yellow, round capacitor?  Should I check the power supply voltage output to make sure this is not causing the problem?

I live in Nashville.  Is there a tech around here who could repair the unit?

Sorry for many questions, I just want to get my baby repaired, since I am the original owner since 1985

Thanks, so much,
BD

ok i found lots of replacement here in holland for the 100uf, 200v types. also radial version (yes!) i included the links.


MY SEARCH & SHOPPINGLIST SOFAR:

i will replace C101 OLD looking -  100, 200V -   = Duch company
i will replace C102 OLD looking  - 100, 200V

i will replace C105 OLD looking - 100,200V
i will replace C106 OLD looking - 100,200V

i am going to replace this with higher voltage capacator : C121 - 2.2, 16V    :   2.2uf 50V Elco Radial (?)
i am going to replace this with higher voltage capacator : C124 - 2.2, 25V   :    


i still have to look for the following as wel as the invertors.

C123 PREC -
C126 PREC  -

T102  looks BURNT -

C114 - 1000, 10V  
C130 - 1000, 10V
