Thank you Daniel, I agree, it does sound good for the money. I won't be sad, if I don't sell it, as I really like it. Worst case scenario, I don't sell it and continue setting up my home studio in the future... when I'm out of an apartment. Awesome mixer.......and the new power supply is really cool...

I'm selling this mixer because I'm not using it anymore. My band has been recording at a large fancy studio in my home town using analog gear, all I have is an 8 channel inexpensive audio interface at this time, so the mixer if overkill. Trying to setup a home studio doesn't work too well in apartme...

Sorry, this mixer is sold. I tried to remove this post and saw no "X" available to do so, so I just updated this post as "SOLD"

While speaker and tubes both make a big impact, mods to the Hotrod amp really do make a big difference... I've done this 3 times now (for three of my customers here in Portland, Oregon). If anyone is interested, check this out: http://www.getupmedia.com/fenderhotrod.html for one of my customer's web...

Been there several times, they havent added much lately and they never seem to have what i want. I love the concept True... this site, while good for what it has, doesn't update too often... and usually those schematics are just a collection of what's already floating around out there anyhow.

I tried MusicParts once to match 2 schematics for slightly different units. No response via e-mail. By phone, I got a "dude" space cadet, who said he'd check and get back to me. Of course he didn't, and every time I re-called about it, I got the same idiot. He couldn't remember the last conversatio...

I suggest Polystyrene capacitors. These are very pure sounding. While this statement may sound subjective, there is much objective truth behind it. Polystyrene caps are very tight tolerance parts and are very temperature stable. I have built some pedals and rack gear with them and the sound really d...

I need a transformer (source) for Re-Amp box....

I'm going to build my own re-amp box. It's actually very easy and will only take about 2 hours... However, the ONLY part I don't have is the TRANSFORMER. A "D.I." transformer doesn't necessarily work well for this particular application. here's why.... This transformer (for those of you who don't kn...

When referring to audio circuits, Class-A always indicates single ended. Single ended, however, doesn't always assume Class-A. Maybe i'm misunderstanding you, but isn't that the other way around? :? Oops, yes. That's what I meant. Thanks for the correction. I did some extensive researching and foun...

Cool. I'm sure you'll get good results with caps. Just to clear up, though, the circuit I drew there would run class A, the output is just not single ended. In most cases class A doesn't have anything to do with topology, just with the particular values of resistors chosen. Then again, certain topo...

Other drawbacks are the volume pot should be reverse log, and the output is obviously push pull which you may frown on, i can't remember if your goals at the beginning of this thread included no push pull. Ned I'm going for a Class-A topology--therefore, I'm going to use caps in my pre-amp (just wi...

Or you could use a choke loaded first stage direct coupled to CF, with more expensive transformer which allows DC on primary, then your gain stage tube would operate nearly its mu, won't lose your db's with high step down, and can use the pri of output as a part of cathode resistance. In fact, this...

Don't transformers introduce phase shift as well, when implemented in the audio path? I have right here in front of me a data sheet from a Jensen transformer I just used in a microphone build, and on the graph that shows "deviation from linear phase," it's up about 1.2 degrees at 20 Hz, with a grad...

and wouldn't transformers introduce just as many non-linearities as blocking caps? Yup! I can understand the desire to use fancy topologies, but when you look at all hte fantastic gear that uses "mundane" (for lack of a better word) topologies, it falls to the side I think. Blocking caps didn't hur...
