BrokenHill,
I just refoamed a newly-acquired set of Mach IIs-always remembered my older brothers set with fond memories. Read from some of your postings that you rebuilt the crossovers. I suspect that mine would GREATLY benefit from the same. I am not an EE, and need all the detail that you can provide for sourcing, part numbers, etc. Pics are also a HUGE help. I can solder and I would like to work through some of these smaller projects before I wreck my dad's old MX100 receiver as a first recap adventure! Can you point me in the right direction? Again, pics and numbers are a HUGE help! THanks, Paul
