Sorry to everyone if some ( most ) of these questions are redundant, and if you don't have time to answer I completely understand.

I picked up a set of stock 19's about a year ago and would now like to have the x-overs rebuilt. I've read a lot of info and opinions, but I think I'm going to go the path that you've suggested using Dayton or Jantzen caps. Unfortunately I'm not a tech at all, so I'll be having someone else do all the assembly. I was wondering if there is any chance you could send me a list of what caps / resistors to use and the values I need to order as I get the impression the exact values aren't available in some cases? I've tried to research the different Altec forums, but there's so many opinions on types ( PIO,metal/poly,film,charge coupled,etc. ) and I have really no idea about that stuff. Don't want to order/use the wrong thing.

I may try and clean the pots but I will be leaving them and the coils alone as you suggested, as I definitely want to retain / regain that classic Altec voicing. I think I understand what has to be done for the grounding of the lugs. Would you suggest leaving the original L-pads in or replacing them as well? I'll print out a schematic to take with me to wherever I get the work done, but I would like to be able to give them as much info as I can on what exactly I want done in order to avoid any issues.

Thanks for posting all the great tips, and for any additional advice you might be able to offer. If not, no worries and sorry to bother you. Thanks and take care.

Hi Mike,

All the info you need are in these threads.All the info you need should be here, but of course if you have any other questions. I would be happy to answer them..

I would use Solen Fast Caps 250v or 400v are fine..Leave the coils ! They very rarely ever go bad, and is a waste of money IMHO.. The parts you may have to source from 2 different places to get the correct values.. Like for the 3.9 Ohm resistors I had to get them at Madisound as Parts Express don't carry them.You may also have to use 2 different caps to reach a value like using 2 8 uF caps to reach a 16uF value..The hardest cap to find will be the 21uf so paralleling a 10 and an 11 uf cap maybe required.
