Calibre 240V/1000W Pure Sinewave Inverter (12V input)
On each of the output transformers at the primary side:
2x HRF3205 MOSFETs on each side of the centre tap
2200uF 16V x2
30A fuse x2
On the isolated secondary side:
Both output transformers secondaries are wired in series
MUR860 x4 full wave bridge rectifier for the HV DC output
IRFP460 x4 H-bridge output for the AC output
1000uF 250V Chemi-Con KMG (fake) x2 in series for the HV DC output
1000uF 35V for the low voltage control supply
PIC16F716 microcontroller (not code protected
) for sinewave generation/AC output regulation

The patient this time: a pair of Philips F9217L-50R speakers from a budget Philips rack/component system from the '80's. The system belongs to my brother in-law… or actually his parents. However, they didn't want it when they moved houses and he liked it anyways, so he ended up keeping it. It's a pretty cool-looking vintage system with a wood/veneer cabinet and shelves for records and cassettes. Unfortunately, I didn't get a chance to take a picture of it or get the model #'s (but maybe next time I visit, if anyone is curious?)
