Finished my HiFi Amp Project

[bluesbubba]

A while back i purchased a Teeco HiFi tube amp at the swapmeet for five bucks. It has two EL84s, two 12AX7s and a 5Y3 rectifier tube . I decided to get inspired and create a guitar amp from scratch for the most part.

I rerouted the mic jack to the front of the amp and combined the selector switch as well. I wanted it to make it look like a real guitar amp so I added a toggle switch and a radio shack pilot light.

I made the faceplate with a piece of anodized aluminum I got at the hardware store. I built the speaker and amp cabinet from plywood and tolexed them.
Every step of the way I was fabricating something. I found a 1950s Bolex 12" ceramic speaker for the speaker cab.

Well here it is:

Wow that's cool - is it cathode- or fixed- biased?

You say its a ceramic speaker but it looks like alot of old alnico magnets used to look (I bet it sounds cool whatever)

[bluesbubba]

It's definitely fixed; no biasing. I thought it was a ceramic speaker by the big "bell" type cap. It came out of a Bolex external speaker cabinet made for projectors back in the 50s, 60s.

I think it looks like an old Goodmans speaker - could be a Goodmans in a Bolex cabinet.

Is Goodmans considered a good speaker:confused:

I don't know haw that speaker ranks, but it does look like an alnico mag to me. If it has a big bell cap on it, it's an alnico. Ceramics tend to be in the form of a big ring.

That's a sweet little project you go t there! That Teesco looks a lot like the Heathkit I'm perfomring a similar conversion on.

Yeah the Goodmans sure are good, they were originally installed in Vox's I believe, but Vox later changed to celestion blues (which were 'smaller' or lighter? for some reason). I put an old Goodmans in a 5F2A I built - it really sings.

I found two speakers at the swapmeet; one was the Bolex with the cabinet and the other was a Bell & Howell with the cabinets; both are for projectors. I think they were both made in the late 50's by their style of the cabs. Got them for $10 each.

That B&H speaker is a Heppner which I found is suppose to be good for DIY cabs, However I like the sound of this Goodman.:)

I'm off to the swap meet this morning for more finds. Wish me luck:D The bug has bit me big time when it comes to building guitar amps and collecting amps.;)
