Hey, what do ya know, the guy just listed it on ebay:
http://cgi.ebay.com/Vintage-1966-Rickenbacker-450-12-String-original-case_W0QQitemZ220495819949QQcmdZViewItemQQptZGuitar?hash=item33569334ad#ht_500wt_1182

He knows it's got a nearly dead p/u, and that the neck is not straight at the moment ...

Thanks, John...
I looked into that stuff and mostly ruled it out due to the fact that there was virtually none of the tell-tale crackling when turning the knobs or moving the switch, and the sound was very consistent no matter where any controls were set or how the cable was dressed (ie all ...

Hey All,
I'm looking at buying a '66 420/12, but the bridge pickup is very low in output. There are no other suspicious noises, and the guitar has mostly been a case queen since the owner got it as a teen. There wasn't time to open her up today, but I'd like to go in armed with more knowledge.
It's ...

I've got a 69 Thinline Tele RI which I love, but I want to have some way to blend the pickups a little bit (without making any irreversible changes). The thought of losing the tone knob doesn't appeal to me, so the 51 wiring is out.

My thought was to use something like Stewart-MacDonald's 5-way ...

Ah ha, this learning thing is pretty cool...
Just for kicks I bypassed the power switch and the noise greatly decreased, so I'm using it unswitched for now. I also tried other things, like routing the AC differently, that didn't help much. I wanted to try different tubes too, but I don't have ...

Thanks, Wolfgang. I put the 22uf/25v cap in across the 1200 ohm resistor that's already there (- to pin3/ground & + to pin2) and the gain is now just right. The problem is it's now unacceptably noisy (60Hz)-- I wonder what may be the problem? Could I have gotten something too hot in soldering?

you'll do better to change the dropping resistor value that supplies the preamp stages, thus changing the voltage the preamp tubes operate at
Sorry, I didn't follow that... which pins would that be on a 6AV6, and are you saying to lower the value?

(BTW, this is a 3 tube amp: 6AV6, 6CA4, & 6BQ5 ...

All right, problem solved! It was the power switch all along (you can laugh at me now), which had apparently opened for "some reason." I simply switched the mains over to the motor's switch after disconnecting the motor, and voila!

I've also successfully converted it to guitar use, removed the cap ...

Hi All,
I made a little boo-boo and I'm hoping you can advise me on how to proceed:
I have 3 of those record players you used to find in schools (you know the ones, they have lids that hinge off). One of them has a mic input, so I plugged my 360/12 in and it's a great little amp (6L6). The other ...

Just wanted to share with you all (ie show off) some pics of the Vox AC4 chassis (with mods) that Terry at D-Lab amps built for me to fit into my old radio cabinet.

I can't say enough about how fantastic this amp sounds! And the little mods he did make it so flexible, I'm having a great time ...

Yes, I see: middle of the road!
Perfect, I'll let you know how it goes...

Thanks, Scott.

Is there any reason in particular that you recommend that one?

Hi All,
I just had an amazing amp made based on the Vox AC4 schematic, and I really love it but it has a wee bit too much preamp gain for my taste. I put a 12AU7 in the preamp and that helped, but the tremolo is tied to that tube and it almost disappears now.

I'm hoping someone can tell me of a low ...

Hey Guys,
I just had an amp made by Terry at D-Labs amps based on the AC-4 schematic (with a few changes), and I absolutely love it! He made me the chassis to spec to fit in an old 40's table radio cab that I loaded with a Weber alnico Blue Pup, and he only charged $275 shipped! It's all PTP wired ...

Hey thanks guys, for all the input.

I did replace the power cord with a polarized one, as well as all the caps. It sounds MUCH better now, with considerably more gain, though the volume is about the same. I'm getting new tubes today, which will help even more I'm sure.

The 4 guys at the ...
