Just finished recapping and testing a TX-6700. Everything seems to work great so here's some pics and a recap list. This should come in handy as there are no parts lists in any of the online service manuals I could find.
Before:
During (note masking tape to hold string so I don't have to figure out how to restring later):
After:
Apart from the caps in the list, markthefixer recommends changing q7 and q8 from 2sa725 to Mouser part number 512-KSA992FBU as a preventative measure.
Please also note that there are some caps in this unit that can affect the alignment, loop filter and ctr freq and separation. They are clearly indicated in my parts list. If you change any of them you may need to have your tuner professionally aligned if you don't have the equipment or knowledge to do it yourself. YOU HAVE BEEN WARNED!
Standard disclaimer: The attached parts list represents a snapshot in time. It's the right list for my unit, yours may be slightly different. Mouser part numbers change and they run out of stock so you may need to make some substitutions. The list should also be inspected by one of the AK gurus (you know who you are) to ensure it meets with their approval. The mods are more than welcome to publish it in the AK recap database if approved by one of the AK gurus.
