For sale is a deflection power transistor module for an Electrohome G08 color vector monitor. This is the same monitor used on a lot of Sega vector arcade machines such as Tac/Scan, Space Fury, and Star Trek. 
This module seems to be complete. It includes the cooling fan, heat sink block, 4 deflection power transistor, and harness connector cables for both to power the fan and for the transistors.  

Unfortunately I do not have any of the hardware to power and test this module, so it is sold as-is.  
For those who want to bid, there is no reserve on the auction price. Shipping only available domestically within the United States.
If you have any questions feel free to shoot me a message and I can try to help.
Thanks for looking!
