Tube Amp Archive

Hey Nuke, I was definately considering that route at first. And while its not out of the question, I admit, I'm a tad bit concerned about loosing any high end sparkle n chime that a 12" may allot over a 15" It may not be an issue but, theres no way from here I can tell. I'm sure that would be great ...

Hello, I was curious to see if I could get any comments from those who have built a Fender type cabinet for a Fender chassis. Specifically, I'd be curious on the starting steps for creating the 30deg angle for chassis with the ubiquitous 30 degree angled 1.75" H chassis. Over the weekend I glued/cla...

I certainly can make some comparisons over time on looking at the bias waveforms. I'll be bringing my stereo 6V6 Plexi up on the bench soon to see if I can get the right channel working (the Left channel was working and sounding wonderful until there was a "pop", and then nothing). That amp has the ...

I do have a scope. I hadn't even thought about looking at the bias signal that way (duh). I usually do not have my amps up at the bench, though, that would make it a whole lot easier to do that - they are always in some car or truck for the next gig. I wanted to hear about how others go about choosi...

Hello, Just thinking out loud about 2 bias circuits I've used in builds, and curious if one makes for a more cleaner bias signal than the other, overall. There are bias circuits that simply use say, a single resistor with a 50uF or 100uF cap as seen in some Fenders, and, there are bias circuits that...

That ring plate around the transformer looks like it would help to stiffen things around the transformer, that might be a little hard to come by or make, well, for me it would. (there is a milling machine in our company shop, though. ) The idea of an L rod (or U) along the width of the chassis was m...

Thanks didit, I will take a look at those Hammonds, and it seems as though those extruded bars will help with that if installed in a good place. Awesome, thanks! I'm well into the building a few stereo tube amps, some with double PT;s and others with one big huge PT in the middle. Don't want to invi...

Hello, Has anyone ever had to hunt down a solution to "amp chassis flex" due to heavy transformers and/or thinner or weaker chassis? Reason I ask is that it looks like chassis could be made thinner these days to save on metal, and also should there be say, a big heavy power transformer that has to b...

Hi guys, If anyone is up for one more visit here. So if I go with a couple of tl806 cabs with an EVM12 type speaker, do you think I will be able to reach low D's and maybe low E flats without any serious issues? I do understand that things will change below 75-83 Hz or so, but, how much? Is it subst...

Thanks guys for your generous feedback, that's inspiring. Funny you mention EQ, and after the Vox modeller. I did infact think that there were some frequency issues that really could use some addressing. Although the guitar plays really nice, there was a little help I thought it needed, and it was r...

Thank you for reiterating on that Colossal, I do infact recall you talking about this and even posting pics. VEry nice looking cabs as I recall. My approach has shifted on this a little bit. My first approach was to be a specific classic tube amp, like a stereo Fender or Marshall but, the baritone g...

Hello Ionnote. Thanks, these are quite interesting. My interest in using a Thiele cab was not so much to get a whole lot of extension, but to give the lowest of notes a good solidity and presence. Since this baritone was exclusively built for playing classical and Celtic like fingerstyle, I set out ...

Thanks pdf64, I am understanding that the TL806 is designed for EVM12 and those with the same specs, having 1.3 cubic feet of air volume. I may have issued winning that war with the boss but, the Eminence EM12 seems to be a good candidate, sounds good to my ears and I believe has the proper characte...

Thanks Nuke, And that is what I originally suspected so was oddly surprised hearing someone say "a significant drop after 1600 Hz". The Thiele cab build does specify a 60 - 1600 Hz "usable range". I thought that was strange. OK, so being that is the case, I think I can put that little rumination to ...

Hello, As I knock around whether to build a couple of Thiele cabs for a future project (another stereo system but for Baritone tuned up to D but with lots of low C's), I get wary of some of the descriptions that surround Thiele cabs. On one hand, I like the idea of supported lows and a smooth respon...
