Hi,
I have a pair of L101 that need some checking since they have been untouched in the last 40 years...
I have 4 questions (for now), as follow:
1 I assume the lansaloy is dead as described on the forum in pervious post; is this the correct replacement : http://reconingspeakers.com/product/jbl-le14a-c8rle14a-recone-kit/#prettyPhoto ?
2 I read also in prvious post that the LE 175 might need some care as a foamy substance is decomposing after serveral years. i tried to undo them but find only what you see on the pictures... and nothing wrong so far. do I need to undo the JBL red wax to reach this substance ? (othe pricture)
3 I have changed in the past the Lpad... I have been adviced on the site to go for 8 ohms (this is on the Ts for the LX10) and 15 W ... but as I turn the knob I do not hear much difference between min and max... is 15 W the correct power for this L pad ?
4 I measured the impedances... The Le 175 are good I think since It says 6.2 ohms and TM says between 5.9 and 7 ohms, but for the LE14A I measured 5.7 ohms and TM says between 5.9 and 7.1 ohms ... is it that bad ? if yes, can something be done ?
below, some pictures, to illustrate.
many thanks for your help
