You can always call me about it at 651-330-9871. I have put together hundreds of Dynakits myself of all varieties over the years.
I would be glad to advise you on what to do, and just as important, what NOT to do.
Starters, if it is old, complete, and ready to play but has not been used for years, you MUST bring up the AC line voltage slowly on an AC variac to avoid damaging the old electrolytic capacitors.
