After swapping out all the parts in the amps, I also set the bias voltage and DC offset and called it a day. They seemed to be tip top!

Now to switch tracks a bit and get over to sorting the acoustics. Classic Penta story here – all eight midrange transducers need new foam surrounds.

This particular chapter takes place in the office lab. A lab where new loudspeaker prototypes are brought to life so it is the perfect place to do this kind of work.

Starting with a shop vac, I carefully vacuumed up the large chunks that were basically just falling off. Then alcohol to remove the remaining residue in preparation for the new surrounds.

I’ve never seen such terrible foam rot before!
