Just talked to Cinemag. They have a run of the CMOQ-4's planned in 4 weeks. I ordered the high nickel version with wire leads.
Oh, I think they should be PC mount. Need to call them back.
Things slowly moving along.

My shoulder is recovered sufficiently for me to be able to spend a few hours on my SissySIT project this morning. I finished the metalwork required to progress further assembly and completed the power supply wiring.
Next step is to bolt the other heatsink to the chassis, then I'll be ready to start installing the PCB.

Two halves assembled:
Ready for the PCB:
Top plate ready for the power switch, input RCA sockets and volume attenuator:

That PCB above the toroid is one of Mark Johnson's power up management units - it means I can have slow start up and a pretty power switch.as long surrounding electronics is more complex than my amp, I'm happy
that's why I'm stayin' in realm of simple electronics and maybe some arduino here and there

Glad to see you back in action fella. Looking very good. My build is on hold at the moment as the garage is too cold to work in at the moment ( and too messy due to too many projects/hobbies on the go)
Making some more progress, kits on order from zenmod.
Was looking at the power supply, and figuring out the parts I need to order for it.
Last night I realized I might have transformers that I could use, after a bit of searching in the garage I found a pair of Plitron, dual 18V sec, 250VA transformers. Bought long ago for gainclones. Saved an order from Antec. Going dual mono PS.
I remember the voltage being a little high in a gainclone, but they were only lightly loaded in that application. PSU designer say just under 24V, but not sure if all the parameters for all the parts are right. I'm going to see what parts I have around to build up a simple PS, and then load it with a high wattage power resistor. See what voltage it really puts out under an amp or so load.

no need for testing, except if you want to test them for (potential) buzz under load
if you confirm around 18Vac no load, do not worry , you'll end where is needed

Very impressive Ray! The chassis looks great, you might need some extra physical therapy to maneuver this beast! 😂
I'd totally buy a replica of your chassis. I don't have the tools or skills to do something as fugly as that 🙁A little more assembly today - now ready to start installing the amp board.
Phew, this thing is getting heavy - good job I thought that some handles might be a useful feature!
