Finish.JPGTandy Optimus 77 Upgrade6108 viewsThese Tandy Optimus 77, though many years old, had never been used. They were in as new condition but the woofer surround had rotted. I replaced the 5” woofer with an inexpensive 4” driver. I made clamps to hold it in place and heavy foam to ensure a good seal. The Xover 4.7uf cap was replaced with a quality cap and additional dampening added. They good but not stunning.
