Welcome. Rock and load! I can't answer your questions on Cornwalls but I'm sure the knowlrdge is here. Rick

I'm going to run right out and get a pair, right after I get my second million. They say that the first million is the hardest to get. So, I gave up on that and am working on my second. Rick

BB, In one of my houses I had a doorway where yours is. What I did was to put a piece of paneled plywood over the door. Then I could get a good seal. Everyones idea of adequate bass is different. If there isn't enough just give that little knob a twist and it will appear I usually have a couple of db of boost for my liking. I know the purists disagree but we are the ones that we must please not them. Also make doubly sure the bottoms are in phase. It's not hard to wire them out( I just did when I hooked up my new biwires and I've had these for twenty five years.) Rick

JC, back in 1978 when I bought my Khorns, I got the raw birch to save a few dollars with the intention of veneeering them when I could afford it. Many buyers did this. I slapped some walnut stain on them and used tung oil to seal the stain. This year I finally "got around" to veneering them. I don't call it refinishing, I call it finishing a project I started 25 years ago. Maybe some day I'll get around to finishing some of the other projects I started over the years. Like grouting the new tile in the spare bath..... Nah, if I finish all of them my wife won't need me around any more. She'll kick me out and keep my Klipschorns! I think I'll start another job tomorrow and buy a few more years. Rick

The Russian tubes are current production. As are the Checz and the Chinese. The Russians used vacuum tubes in military hardware against the EMP of a nuclear explosion. Tubes would blink them come back up. Russian solid state could not take the pulse without frying. Us technology uses EMP hardened solid state. I believe that the machinery ain the JJ plant was purchased from Mullard when they stopped making tubes. The Russians, I believe use some RCA and some Phillips tooling. I'm sure they all had spies copying the best of all manufacturers methods which were then mucked up by the Commies. Now they can ask for and recieve help to produce a better product. Rick

Any time you have electricity flowing through a conductor you have a magnetic field developed. The straight path of the solid core VS the twisted strands of audio cable will have a larger field as the twists tend cancel out each other's field. Another factor in high frequency transmission is the surface effect of the conductor. A solid wire has little surface as compared to a multi-strand cable. Rick

Sebastiano, Welcome to the forum. Where are you in Itilia? Rick

I got some silver plated 14ga and 18ga teflon coated aircraft grade wire that I am going to make into a bi-wire set. Took all 4 100 foot coils out on the lawn today and twisted them. First the 14ga, then the 18ga, then both together. I started twisting by hand but it was taking forever and was too tedious for my AADD.There had to be a better way. I got out my trusty drill, chucked up the strands and twisted. Worked great. I just wonder what the neibors thought, "What's that fool doing now holding that drill in the air? I'm sure that they could not see the wire tied to the column of the entryway. I'll terminate them and install them during the week. I've got an archery tournament in the morning and the race is at my favorite track, Martinsville tomorrow. By the way the 14ga OFC wire was too much for the squaker in the Khorns so I went back to OE. I'm going to try some of this silver plate next. Rick

Has anyone ever put a scope on the output capacitor of the PS and seen the audio signal there? A picture of the scope screen would help to explain Leo's theory. I was reading (really, no pictures) that the voltage drop across a 5U4 is greater than the GZ34 giving the latter more power and dynamics.: "Rectifier I have used the 5U4GB General Electric tube for this amp but have also tried a Mullard GZ34 and found that there are some benifits brought with it in terms of bass definition and an increase in the top end , presumably because of the increased B+ due to the lower voltage drop across it of around 20v - I finally setttled on the 5U4GB for better sonics and what seems like better drive overall. The 5U4 GB has a voltage drop of 44v across it and is 1970s vintage."(from Audio Illusions by Derek Walton) http://indigo.ie/~walton/300b.html Rick

I don't want to be "picky" but, do not use solid wire for good audio reproduction. Solid wire is great if you are sending 120V at a fixed frequency to an appliance. However audio signals vary in frequency and amplitude with most content at 1V or less. At the higher audio frequencies hysteresis losses and eddies will occur in the solid wire resulting in a flat sound. Even for in-wall applications a good quality stranded wire of the proper guage for the length of the run should be used. Monster and others make wire for these applications. Solid wire is however used in some 70.7V line level sound systems. However this is far from "hi-fi". Rick

"Does it matter what I think? You betcha !" Ditto. Rick

Craig, What would you recommend? EL84Ms? NOS can be expensive. Rick

Got in today. Thanks Gil. Rick

Yea mOOn, The Marlins are going to crush those damn yankees. Rick

Nuff said Rick

That site must have exceeded it's bandwidth. All I get is a "can not find server" page. I'll try in the AM agian. Rick

"Very nice indeed! Is it home-brew or a DIY project from another mom 'n' pop tube firm? Obviously tube rectified with lots of iron...tell us more!" It is from a mom and pop outfit. Some of his past customers said although he's a bit slow, there is good quality in the parts and workmanship. "Man,your brass is tarnished. Shine them up and get some mouthpieces! " Those are ghosts from the past picked up at thrift shops. We wanted them to look old. I am keeping an eye out for inexpensive mouthpieces to complete them. "That little white thing sitting on the mantle?" Yea BigB, In my mind that little valve powered StryoSup-R-Amp puts out 600 watts without the afterburner. When it gets here I'll take more pics. Rick

Really I wanted to try a higher power SET than the EL84 that I have and this one for $425 fit the bill. It will give me a better idea of SET v PP and I can go from there. It will also give me an inexpensive platform to experiment on. Rick

My wife likes it, she hates messy looking wires. Rick

Kind of an ecletic mix tonight: Simon and Garfunkle's greatest hits Heart Ellington at Newport( scratchy but electric) Horowitz Plays Rachmananoff Alan Jackson High Mileage(CD) I like everything but Rap and, especialy, opera. Rick

Type in AA schematic in the search box above. John Albright provided the AA schemitic for us not long ago. rf3iicrazy is the poster. Rick

John, does this sound right to you, not knowing the Q of the tweeeter: 10uf; 24mh; 8ohms? With that peak just one octave below the crossover point I can see the usefullness of this filter in the circuit.If the values are correct, I'll play with it. It's easy enough to put in and remove. Rick

Hey mOOn, Check out these Klipschs for your HT. You won't need those two Subwoofers. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3052580170&category=14993 Rick

A good coupling will always make your day! Rick

Arthur I just thought of something. Check the seal on the bass bin doors just for kicks. If it's leaky the K-33 won't be properly loaded and that could introduce some frequency doubling which would sound like excessive bass. Just a thought that crossed my mind. Rick
