Try as I might my old Ungar iron and roll of SolderWick fight a losing
battle against the leads. I've got a 70W digital-control solder station so
I ordered a much heftier chisel tip element for it. The elements I have are
only good for tiny surface-mount chips.
Replacement transistors will be my next issue. Unmatched MRF458s (per
Mike) at about $50, matched at about $60, or matched MRF454s (per Paul at
TenTec) for a whopping $125.
The 454s have higher current/power ratings and slightly higher gain at some
frequencies. These are what TenTec uses for in-house repairs.
Decisions, decisions...
