Allan Songer Posted November 6, 2003 Share Posted November 6, 2003 I did rewire a tonearm a few months ago. But that was only because I screwed up the wiring changing out a bearing. Bennie Green is my favorite trombone player. I am reading the new James Lee Burke novel (juat finished Joan Didion's "Where I Was From"---GREAT book!) I like having sex.

maxg Posted November 6, 2003 Share Posted November 6, 2003 Alan and Fini, Just 2 old solders reminising. I can solder, but badly. I did make a pair of speakers though - bad with metal - good with wood. Quote Link to comment Share on other sites More sharing options...

sunnysal Posted November 6, 2003 Share Posted November 6, 2003 who fux with flux? I, blissfully ignorant, buy equipment and enjoy listening to music. YMMV, IMHO, LMAO, your hovercrafy is full of eels, etc. Quote Link to comment Share on other sites More sharing options...
sunnysal Posted November 6, 2003 Share Posted November 6, 2003 I have no bones to pick with that statement mark, I understand very well the desire to understand more about this obsession of ours. I, in fact, spend a lot of time reading about technology in the hopes of understanding these issues better. In the end though I am still stuck with "my ears are the best judge"...not because my ears are "right" but because I have to accept them as my only true frame of reference, and that I am unable yet to predict how anything will sound by looking at any specifications I have seen published about any components. even units that seem to "test poorly" can sound great, in the subjective sense, to me. warm regards, tony Quote Link to comment Share on other sites More sharing options...
rigma Posted November 6, 2003 Share Posted November 6, 2003 Mark or Craig, Explain what the below means and how to change it. I now have scope & function gen. I want to test my newly rebuilt MK-IIs. Also how do you set bais for class "A" or more toward that using the scope? My amps are wired in triode with K-88s and Triode(Brand) driver board with AC balance. Rigma "Although these have been tuned for a pretty narrow band top end (very smooth rounded leading edge at 20KHz) I like my MKIIIs tuned much "hotter" at the top. I try to get the full-power band out to 30KHz which will be reflected by a steeper leading edge with just a tiny overshoot, no ringing. It's always a compromise."

NOSValves Posted November 6, 2003 Author Share Posted November 6, 2003 Rigma, I owe someone a Scope lesson. Mark did it for me and its my turn. But for at least a week and a half I'm going to be just to darn busy ! If you want we can do it like Mark did with me. Send me some closeup photo's of your Scope and function generator. The photo's need to be clear enough so I can make out the controls. This way when were talking on the phone we are both looking at the same knobs and switches. You need 2 - 8 Ohm 50 Watt resistors the type that have a all alluminum body for heat transfer ! They will get hot ! In fact attaching them to some type of large finned heat sink is a good Idea ! I take you have BNC cables to RCA adaptors to hook the signal generator to the Amp if not Radio shack has the stuff for that. Get all your ducks in a row and we will find time to walk you thru it ! Craig Adjusting those responses are fairly easy through the feedback circuit. A scope and ears are required. Quote Link to comment Share on other sites More sharing options...

rigma Posted November 8, 2003 Share Posted November 8, 2003 Mark, Can you are anyone else recommemd any good book or reading material relating to testing and tuning tube amps? MB Quote Link to comment Share on other sites More sharing options...
Painful Reality Posted November 8, 2003 Share Posted November 8, 2003 You might consider "Beginner's guide to Tube Audio Design" by Rozenblit. Chapter 10 is on testing amp and fixing problems. You might also consider Valve Amplifiers by Morgan Jones. A Google search might also get you very far. Quote Link to comment Share on other sites More sharing options...
rigma Posted November 8, 2003 Share Posted November 8, 2003 painful reality, Thanks for the heads up, I just placed an order for both on Amazon. MB Quote Link to comment Share on other sites More sharing options...
NOSValves Posted November 9, 2003 Author Share Posted November 9, 2003 Rigma, Found a link over at AA about scopes on Tektronics sites check these out pretty good stuff http://www.tek.com/Measurement/App_Notes/76_16672/eng/76W_16672_0.pdf http://www.tek.com/Measurement/fundamentals/scopes/literature/XYZs_of_Scopes_English.pdf Quote Link to comment Share on other sites More sharing options...
mike stehr Posted November 9, 2003 Share Posted November 9, 2003 Yup. If your interested in using scopes, the site is a great place for that reason. I've been poking through it, and really should pay more heed to those primers, but I keep falling asleep. Sad. Nonetheless, I'll keep struggling.
