Modules and chassis received!
Everything in good condition because of the very good packaging by LC
One of the aluminum corner guards was dent during travel doing it's job very wel by protecting the precious cargo, wel done!
The casework is stunning, very high grade and has an impeccable finish!
The modules also look very professional and high quality, can't wait to start building... :-)

Is there a list with preferred materials (BOM) available for assembling everything toghether with two Hypex SMPS1200A400 power supplies (like: power switch, (RCA / speaker) terminals, mica insulators, etc..)?

Thanks for creating this peace of art LC!

Regards, Edionysus.

Hi Paul

Glad that the package arrived undamaged and Al protective corners did their job properly.

Well the holes are made in standard sizes to fit RCA chinch, WBT or similar speakers terminals, 230 mains connector and small size mains power switch.

First One modules and SMPS1200 fit exactly, bolts were added in the package. 2 mm front plate green LED-s also included in the package.

All these parts can be ordered by Farnell or to buy at your local electronic shop and are compatible with parts from many different producers, that's why I didn't specify any of them particulary.

Looking forward to see your built.

Best regards, L.C.

Started an assembly of a new First One amplifier for a friend. It's a generic dual mono version with two SMPS1200A400 and DC Sense protection. Pics will follow soon.

Hi tubo

Not necessarily, but some sort of passive attenuation would be recommended between the two.

Serial 2,2 k fixed resistor with shunt 10 k/log potentiometer to GND is a great solution for volume regulation, tested.

Draw the sch to see if you know what I mean.

Regards, L.C.
