Default My Multi-Channel mosfet amplifier build (13 ch)

hi guys,
i was looking for a multi channel power amplifier so i had started to build my amp that based on 16 mosfet amp modules, 6 of them are bridged for powerful channels.

The main parts + Links:
- Chassis from Queenway store. (Ali express), Quani is a great guy, he customized the KSA-50 chassis to "Marantz style". (Link)
- Capacitor boards - they could fit up-to 35mm caps, i installed nover caps 10000uf/50v (60,000uf each board) + USSR 9.1K 2W resistors that i already had.
(Link)
- Transformers - Antek 1000VA - 30V x 2 for 10 Mono channels. (Link)
Shilchar 600VA - 25V x 2 for bridgeable channels. (Sorry, Friend bought it in local store in India so i dont have a link).
- 16 Motronix mosfet amplifier modules. (Link)
- 3 Motronix BTL boards (Link)
- DC protection boards (Motronix), one support 13 ch and the second is 6 for the BTL. (Link for the 6ch, i didn't find the 13ch board)
- Connexelectronics soft-start V3 (Link)
- Spacers, Rean RCA, Brass binding posts, Ceramic PADS, Dow Corning heat compound, Wires, etc... you can find it easily on eBay, if someone need any help to find please don't hesitate to ask.

Lets start :-)
