capacitor question on lundahl pulse transformer input

[bazz]

hi ive recently replaced the pulse transformer in my metrum octave dac with a lundahl 1572 ,it requires a .01 cap on the input which i fitted ,then i noticed downstream was a SMC capacitor ,the value i know not(KA5 ???) ,my question is should i bypass the SMC cap with the one ive fitted,or ditch the one ive fitted and use the SMC cap ?

this is the original pulse transformer


and the new one -input below the 2,earth below 1,both connected to the resister ,input also connected to the cap



looks like KA5 printed on the cap ?

looks like KA5 printed on the cap ?

if you cannot find service info for the board, then you will have to remove the cap and measure it with a capacitance meter
it's value could be anything between 10nF and 100nF (.01uF to .1uF)

Probably 100 nF, confirm by measurement.

many thanks, looks like its the wrong value,so ive bypassed it with great results,thanks.
