Tube Amp Quandary - Need Help
In my limited experience I have found tube amplifiers to sound vastly different when mated to different speakers of varying loads. For example my Jadis Orchestra Reference sounds excellant with my Harmon Kardon Sixtys or my Triangle Titus's, but a... 
Burning In Preamp ???
Running the amps with no load can potentially damage them. It is not necessary. 
Burning In Preamp ???
Yes. Happy Listening. 
Tube Rolling with 6SN7 tubes...?
5692 RCA "red bases" have a seductive and sweet midrange. They do not, however, allow for higher plate voltages (which means that if a GTB is reccomended because of higher plate voltages, the tube life of the red base will be shortened). NOS Sylva... 
How Much Push/Pull Tube Power for Maggies
IMHO if your planning on using tube amplification with low impedance speakers, try the Paul Spelz autoformers. You'll be glad you did. 
DUNLAVY,S SPARE PARTS.
I believe Audio-Video Logic, in Urbandale, Ia, bought all the spare Dunlavey parts when they went out of business. You could inquire there. They should be able to help you. 
Atma-sphere OTL S30 Amp with Green Mountain C3 sp
Try asking Ralph Karsten's opinion at Atma-Sphere.com. He might know better than anyone else, unless someone has that actual combination in usage. Sounds to me, however, that it may produce an excellant match. Happy Listening! P.S. I am using the ... 
DK Design VS-1 Reference MK3 Noise Issue
You wouldn't by any chance be connected to cable FM? That is notorious for ground loop hum. 90 db speakers are pretty sensitive, so, I agree, going for phono stage quality 6922's would be worth a try. I like Andy at Vintage Tube Services, for his ... 
Jadis Orchestra bias adjustment
First, using a digital voltmeter, measure the voltage across the 5U62 resistor connected to the output transformer. Adjust the 22K ohm pot untill the meter reads between 95 and 120 mv. Using another digital voltmeter connected to each of the YELLO... 
Tubeaholics please advise
I have a pair of friends who each has a large stash of vacuum tubes. I will check with them on the availability of the 6LF6 tubes which you require. 
need help troubleshooting
Check tonearm wiring, particularly the ground wire, including the cartridge /headshell connections. I hope this helps. Happy Listening. 
looking to make homade pc
Try to locate an A'gon member named Ernie Meuner (sp?) whose moniker is Subaruguru. He sells DIY pc's and powerboxes that are fun and easy to build, sheilded too, and not extravigantly expensive. 
How to horizontally bi-amp Maggies
As I understand it, one stereo amp feeds R and L woofer posts, while the other stereo amp feeds R and L mid/tweeter posts. In the application that I had them in, this sounded way better than bridged mono. If I am incorrect, please, someone, correc... 
Would the Revel F12 have any problems with...
The Revel F12's are a definate overacheiving speaker. At $995 Canadian, I would think that rates it as a "steal". You are in a perfect position to audition them in your own listening room if your dealer lets you, and compare for yourself. (He shou...
