| Fine tuning Azimuth - Very postive results Raul, an order of magnitude is a factor of 10X. That would be 1000% better. 25% is 40X LESS than that; or 4 orders of magnitude smaller! Of coarse I could be full of it; since I listen to equilizers strung together by nasty, distorting transformers. | |
| Cary SLI-80 Tube amp suddenly blowing fuses When you bias an amp you are setting the idle current in the output tubes. This is measured in mA. I think the confusion comes fronm the fact that different manufacturers use different methods for measuring this current. The Cary measures this dir... | |
| An obscure question..... As a satisfied owner of the K&K phono pre I concure with the Oz. Dave's differential parallel feed linestage is pretty special too! | |
| Cary SLI-80 Tube amp suddenly blowing fuses Probably won't if you don't stick a "bigger" fuse in it. | |
| Cary SLI-80 Tube amp suddenly blowing fuses Could be a bad rectifier tube. If they short it will pop the AC fuse. Happened to me with a NOS RCA GTB. Tube tested OK on tester, but the higher voltages in amp would cause it to short. | |
| D'oh I killed my cartridge...now what? I had a dream the other night (nightmare may be a better discription) where I killed my Shelter 90X. Bent the cantiliver and tried to staighten it. Awoke with a sick feeling in my stomach but relieved that it was only a dream. Hope to hell that I'... | |
| am/fm tube tuners A Fisher 100b with some simple mods (replace power supply diodes with FREDs, quality coupling caps and a good tune-up, maybe replace the 12AX7 output tube with a 5751) will sound wonderful. These can be had on ebay for ~$200. Expect to pay $500-$8... | |
| Krell amps and Tube Preamps - enemies? Oldpet, the bass is just fine. The preamp is transformer coupled; it can't leak DC. Also, since it is a differential parafeed design, there is no DC at the input of the output transformer. That is how they are able to use a high quality mike input... | |
| Krell amps and Tube Preamps - enemies? Oldpet - I purchased the RA line stage as a kit which requires doing all the soldering. Most of that is to PC boards and the instructions are very complete. If this is a problem, it is available already built. I now have over 350 hours on mine and... | |
| Krell amps and Tube Preamps - enemies? Oldpet - log on to: www.kandkaudio.com or check out the K&K Audio sponsored forum over on the AudioAsylum. There was also a series of articles published in AudioXpress by Dave Davenport under the title "A Line Stage Odessy". A very complete ki... | |
| Balanced preamp recommendations Check out Dave Davenport's line stage kit at Raleigh Audio. It is a transformer coupled balanced parallel feed differential design that has worked "magic" in my system. This kit (also available built) has been the subject of a series of articles i... | |
| Krell amps and Tube Preamps - enemies? I just finished building and "burning-in" a Raleigh Audio line stage kit that was featured in a series of articles in AudioeXpress magazine. The circuit was in part inspired by an article on parallel feed circuit topology by Lynn Olson that appear... | |
| Am I crazy - tube pre-amp with receiver?? That's what's "crazy". I'm using one of the component inputs on the Cary. Setting the volume control on the Cary to ~10-11 o'clock puts the volume control on the line stage @12-3 o'clock. Right now the line stage is driving my new 2A3 SET amp that... | |
| Am I crazy - tube pre-amp with receiver?? I recently built a new line-stage from a kit. To test it, I connected it into my system ahead of my Cary SLI-80 integrated amp. Surprize; this sounded way better than the Cary alone. BTW - this is one sweet preamp: tranformer coupled with Lundahl ... | |
| Need a Preamp Recommendation Can you use a soldering iron? Check out the Raleigh Audio Line Stage at www.kandkaudio.com This unit has been the subject of a series of articles in AudioXpress magazine; the last in the Nov. 2004 issue. This preamp kit (also available built) uses... |
