90 restoration
#86

One last thing: when a speaker is reconed and gets a new modern cone with a new modern spider, it, as we know, improves the sound.
However part of the improvement is a very strong deepening of the bass to the point of over powering the other frequencies so even at the mas treble the sound is too deep in the bass.

It almost calls for some artificial low frequencies reduction, which would be another slight change in teh schematic I haven't done so but some of you might want it if this is gonna be the case. Possibly this capacitor from detector to the 1st audio could be played with....dunno.

It sounds well right now but a bit too booming. And once I assembled the speaker in the cabinet, it is really....booming Icon_smile
When I connected the 95's speaker the booming went away and the treble became very pronounced so it had to be dealt with by trurning the tone control one notch down.
