    ALAMO REVERB UNIT Mod?

    Heh...yeah. My schematic. Another question on this....are the two .005mfd caps off the A/C in lines to ground really necessary? Or do they pretty much amount to a double death cap?

    Impedance transformer...HELP!!

    Apologies. Been really busy with lots of projects and divorce proceedings. I hooked it up to a multimeter and it gave no readout. So I'm guessing its dead.

    Impedance transformer...HELP!!

    I'm trying to wire this little impedance transformer into a circuit to take a hi-Z signal and convert it to a low-Z input. It should go from 50K ohms to about 500 ohms. I pulled it out of an old Archer brand inline adapter that went from XLR female to 1/4" male. But I can't remember how it was...

    Here's the coding. I've been reading mixed info on it. Could handle the power... might not.

    Rola alnico

    A friend of mine salvaged this 12" Rola out of a Hammond tone cabinet. <a href="http://s27.photobucket.com/user/irishronin/media/20150113_171347.jpg.html" target="_blank"><img src="http://i27.photobucket.com/albums/c187/irishronin/20150113_171347.jpg" border="0" alt=" photo...

    anyone having trouble getting through to Weber?

    Thanks TA! I was just confused and a little frustrated that I couldn't get in touch. I know it wasn't anyone's fault...as I said, it was just a silly computer fluke.

    Replacing a voice coil...

    So I have this old 8 ohm 15" CTS alnico in an Alamo Fury bass amp. It has the aluminum center cut dustcap. I use the amp for harp, so I'm gonna replace the dustcap with a Weber H-dustcap which is specially designed for harp and diffuses a lot of unwanted highs. I'm wondering...while I have...

    I don't understand how Emi gets 35W out of a 1" voice coil....that's what mystifies ME....

    anyone having trouble getting through to Weber?

    I just said in my last email that I'd tried emailing and calling several times with no response, and reiterated my question. And I got the apology and the answer I needed. I have a feeling they're gonna be checking their spam folders a little more often now....simple fluke problem that's been...

    Need quick Super Reverb speaker help.

    Actually...on paper, the 1028K's are rated a little higher for wattage. 35W as opposed to the 30W on the Blueframes.

    Need quick Super Reverb speaker help.

    Eminence Blue Frames oughta do you good. They kick the crap outta current production Jensen P10R's IMO, and though they're getting harder to find these days, NOS ones still go for about $100 a speaker...

    anyone having trouble getting through to Weber?

    EL84 to 6V6 adapter???

    Don't suppose this might help me in the 6AQ5 department would it?? Or might I be better off wiring up a simple 9-pin to 9-pin adapter for a 6P1P...

    EL84 to 6V6 adapter???

    Well...so is a 6AQ5 (EL90) for that matter in 7-pin...and I think they're actually shorter than either 6V6's or EL84's...hmmmmm...

    EL84 to 6V6 adapter???

    Drops output 50 to 70 percent they say... But I was just thinking in terms of getting one for the housing to rewire to purpose. I wrote YJ and asked if they had a reverse adapter in the works... They said no, but they'd pass the suggestion on to R&D...

    EL84 to 6V6 adapter???

    So probably something more the size of a VHT adapter housing? Or a YJ short perhaps?

    EL84 to 6V6 adapter???

    Oh yeah....they're still making them...in several varieties actually. Some other folks are too... http://www.yellowjacketstc.com/ http://www.vhtamp.com/products/vht-accessories/special-6-el84-adapter...

    EL84 to 6V6 adapter???

    I was afraid of that....dammit....ain't fair that it's easy to adapt a BQ5 to 6V6 circuit, but damn near impossible to go the other way around...

    EL84 to 6V6 adapter???

    Actually...when I first rebuilt the cab...I very stupidly transposed the V1 and V2 tubes by accident...power tube in preamp socket and preamp tube in output socket... No sound came from it...luckily I realized what I'd done quickly and got her shut off before anything was damaged.

    EL84 to 6V6 adapter???

    What if I managed to get one of these adapters made with an additional 660 ohm resistor inside it on the mini-noval 3 pin?

    EL84 to 6V6 adapter???

    The width I'm not really concerned about....here's an underchassis shot of a Zoo Deuce. The EL84 is second tube from the left. And that's not an original OT...it's a Hammond replacement, and much larger than the OEM one. But You're right about the tube length...the cabinet isn't original...
