Newbie here. I'm interested in the 18T but really cannot find anything about the electrical system apart from; "Three power supply systems are used on the Yak 18T. They are: a direct-current of a voltage of 28V, an alternate single-phase current of a voltage of 115V with frequency of 400 Hz and alternate three-phase current of the voltage of 36V and frequency of 400 Hz. The primary system is a direct-current system with the GSR-3000M generator and the 0NKBN-25UZ storage battery. The sources of alternate current are the PO-250A (115V) and the PT-200Ts (36V) converters." I note there are conversions to remove the generator and install a SK35 alternator. What equipment used the 115v and 36v? Thanks. Rod.
