I just gotta glue on a pair of Klipsch emblems and 4th coat of tung oil on one of the speakers then I will be done with these. Recapping the crossover made a big difference. Not too shabby for a garage system.

Nice looking work there, Min. What did you use to recap the crossovers? I'm thinking my Chorus could use some of the same kind of treatment.

My crossovers are the original AAs. Very minimalistic with only three caps on each. I used ASC oil-filled caps from Allied Electronics and NOS Russian PIO caps that I had in my parts bin. Don't know if it makes any difference to use oil in crossovers, but I used them anyway since they were cheap. The biggest difference was the bass. There is more of it and it got a bit tighter.

Very nice job Min.

I have thought of freshening up my LaScalla crossovers, but, I think I am going to convert them to Type A network. That puts one less cap in line with the tweeter. I also thought of changing the tap on the autoformer to reduce the level on the midrange. To do this though, requires adding a 25 ohm resistor in parallel with the midrange input, to retain the proper crossover point.
