I just finished assembling the Elator to compliment my Ceriatone OTS 50. Here is a list of some of the parts I used:
Chassis - https://www.aliexpress.com/item/1005003694415425.html
I found someone local to engrave the front and rear faceplate
Power transformer I ordered from Ceriatone that is used on their C-Lator - send them an email for pricing
Most of the components were purchased from mouser, the LED and 20 gauge 600v solid core .wire from Amazon. The shielded wire was 18AWG 600v
The chassis comes with feet but I installed taller feet I had on hand to clear the amp handle.
For some reason I cannot upload photos.....

Hi steveb787, look for a Rackmount enclosure that is an 1U chassis with these dimensions - 430x220x45mm.
A quick search got me this one - https://www.aliexpress.com/item/1005009118241921.html?spm=a2g0o.detail.pcDetailTopMoreOtherSeller.5.7377N6a1N6a110&gps-id=pcDetailTopMoreOtherSeller&scm=1007.40050.354490.0&scm_id=1007.40050.354490.0&scm-url=1007.40050.354490.0&pvid=2cd18fed-0e46-4b2e-8d98-e9fe9b67b190&_t=gps-id:pcDetailTopMoreOtherSeller,scm-url:1007.40050.354490.0,pvid:2cd18fed-0e46-4b2e-8d98-e9fe9b67b190,tpp_buckets:668%232846%238112%231997&pdp_ext_f=%7B%22order%22%3A%223%22%2C%22eval%22%3A%221%22%2C%22sceneId%22%3A%2230050%22%7D&pdp_npi=4%40dis%21CAD%2137.54%2133.79%21%21%21192.31%21173.08%21%402101c59817524071247624987e7998%2112000047979664262%21rec%21CA%21711566508%21X&utparam-url=scene%3ApcDetailTopMoreOtherSeller%7Cquery_from%3A
I usually put a BOM together but I could not find one for this project. I quickly put this together so double check the values before you place your order. I included non Mouser orders so maybe you can find items based on the product number locally.
