Dual mono amplifier, recapped and adjusted to spec. 725 preamp also recapped and the 715 tuner I didn't mess with because tuner.
Lots of parts replaced/upgraded, new thermal paste on the output transistors and added heat dissipation on the amplifier boards. I really like it but I've got too much stuff...
