me and my looney ideas....

anybody taken an orphaned speaker and turned it into a guitar amp? i have a jensen 3 way nobody seems to want that's meant to be driven with about 10w or so. i was thinking it wouldn't take much to put metal corners on it, slap a handle on it, drill some holes for the control shafts and mount a mono tube amp in the speaker cab. the cab has a removeable back so it can be open back or closed back.

just a wacky way to use some orphaned gear. anybody done it?

I'm turning a Caliphone phonograph into a guitar amp. I pitched the record player, kept the nice little SE 6BQ5 mono amp and Jensen 12" speaker in it's cabinet. I'll mount the amp right into the speaker cabinet and make a little control panel for the jack and controls (they were mounted in the record player chassis). So, yes. Something similar. Go for it! Guitar speakers are usually not full range, so the 3 way may not be ideal for electric guitar, but it might be really well suited for an amplified acoustic guitar or even a mini vocal PA set up.

My project sounds OK so far, but I'm fighting a terrible hum problem that the amp had even when it was all original. I've replaced the PS caps, the cathode bypass electrolytics, a few plate load resistors that had drifted badly, and repaired the broken connection on the feedback loop. Each of these made an improvement, but it still has nasty hum. I won't further hijack your thread... when I've got the motivation I'll start a new one.

...probably ditch the tweet and mid and just use the woofer. Depending on the vintage and model a Jensen driver could be quite the thing. Watch the joints. A lot of speakers weren't built to take the lugging around and general abuse of a typical amp combo cab.

I've got a speaker I'm thinking of doing this to as well. If I put it on it's side it's a bit bigger in each dimension than an old Fender Deluxe combo cab. I will probably cut a slant into the face and redo the front baffle to hold two drivers. I realize I could whip up a cabinet from scratch without much effort but I might as well use what I have handy.

i've done this a few times when i had spare time in the past - now i rarely do. anyways, as far as using tweeter, one time i had a 16 ohm fullrange driver and used a same 16 ohms tweeter in parallel (8 ohms load for the amp), and it made very interesting sound. with a few effects pedals, i usually had a blast all night long...having fun. :D

Sure!
(my favorite candidate is old Bell & Howell speaker boxes)
I would suggest your check out ax84.com
For a 10-watt speaker I would consider a P1 or P1 Extreme project
(single ended EL84 or EL34)
Lots of project options available there actually
WOT

spent some time on ax84. lots of interesting projects there.
