Title: Schematic request: Magnatone M15 (Solved)
Post by: Cinematographer on July 19, 2023, 11:10:49 pm: Hello hive mind,
I am looking for a schematic for a Magnatone M15 with Three speakers. The schematics that I hae on the web don't cover the early 3 speaker model and the later models use different topology especially in the reverb. I know this is a long shot.. Thanks for any help in advance.

It is technically 5 speakers: 3 8 inch speakers and 2 tweeters my faceplate is unreadable but the amp looks like this photo I found on the web.(https://images.reverb.com/image/upload/s--aUQ7kod5--/a_exif,c_limit,e_unsharp_mask:80,f_auto,fl_progressive,g_south,h_1600,q_80,w_1600/v1453837974/xmrn3wgcwkziuycowwjc.jpg)

It had a metric ton of rotten foam and various bug bits along with broken tabs on the PT bell end. There have been some ahem... mods so this schematic will be invaluable. Thanks again! I was able to bring this into photoshop and enlarge it and improve the readability. I'll post it here for anyone who finds it useful.
