Bryston BR-20 screws

@danny00032 ,To remove the cover on a Bryston BR-20, you will need a Robertson screwdriver, specifically a #1 or #2 size, as Bryston often uses Robertson screws in their designs.

Please take a picture of the screws to your hardware store to ensure you get the right one. Maybe take your unit to your hardware store to ensure you purchase the right tool.  Or, call any Bryson retailer and ask them  

You can purchase a Robertson screwdriver from the following options:
• Lowe’s: Craftsman 2-in Square/Robertson Screwdriver Bit Set, includes sizes #1, #2, and #3 .
• RobCosman.com: Original Robertson Screwdriver Standard #2 (Red), known for “Cling Fit” grip .
• Home Depot: Knipex Robertson R1 Screwdriver with ergonomic handle .
• Amazon: Owl Tools Robertson Square Head Screwdriver Set, multiple sizes .

Maybe the Owl Tools Robertson Square Head Screwdriver Set (5 Pack in the Following Sizes: #0, #1, #2, #3, and #4) Forged Steel with Magnetic Tips & Soft Ergonomic Handle available from Amazon.

In any case, I suggest you take your Bryston unit to your local hardware store and find the exact screwdriver you need to remove the cover.

go to harbor freight tools, get a screwdriver kit with the size bits you need, something like this

Well for anyone searching for this info I found that the correct key that is needed is a STAR T-9 TORXS. Everything looks good on the inside just some ribbon cables that have a little play in them making a bit of noise when you move the unit around.

Thanks all for trying to help, much appreciated!
