These are the ones I’ve used, and others here as well with good results. Can’t find them now on fleabay. Use to be listed regularly.

What a gorgeous set of 3s! Those will clean up nicely! For the pots, contact baco99 (Brian) on Audiokarma. He also sells them.
I’ve also used the Mellotone and it a virtual perfect match to the original.
Cheers!
I had to make new grill frames for one of my set of 3s and used 1/4 MDF. My other set of 3s have 3a frames and used one for measurements. With the Melotone Saran material on the frame. It’s fits nice and snug. No Velcro needed.
Call Brian at Holthill Audio regarding the PA amp.

No site. I organize the meet twice a year. You just come, bring a system to demo if you want, or just come to enjoy the other demo systems, maybe buy some vinyl or parts, and spend the day with fellow audio heads! It’s a lot of fun. Cheers, Glenn
