I am a semi-retired electrician, not an electronic tech, and my computer skills are as limited as my typing skills but thank god i stumbled on this well-written,intricately-detailed,easily-understood manual. i am undertaking a restoration project on the ar3a`s i bought in 1973 while stationed in germany. I had a woofer reconed about 10 years ago and just purchased a replacement for the other one from abtech because I didn`t know if reconing is still available.I also bought 4 new `pots` that turned-out to be 8ohm L-pads.Should I return them or use with 25ohm resistor? Anyone who has the time and pity to help would be appreciated. thank you and thank you to the authors
