Here's "Marsha," a Marshall JTMC410 that I loaded with four fully functional vintage CTS speakers (3x '69 1x '74) pulled from an SVT 810. Why? It's a sturdy sealed cab that has almost exactly the same inner volume as half of a flatback 810 and is much, much more portable. I upgraded the handles from the resonant and cracked stock plastic handles to larger metal ones that make carrying the cab a breeze. I also added a foam backing. Some of the speakers have replacement dust caps but are still totally functional. You can't see that through the grill cloth anyways. It'll break up nicely underneath your tube amp of choice up to ~120w and would make a great alternative to the fridge for jams and bands with reasonable volume.
8 ohms, 100 w RMS handling, 24" wide x 24" high x 12" deep
Any questions? Just ask me!
