| Vintage speakers from the 70's and 80's Get thee to a Snellery!Seriously, I am VERY impressed with the Snell Type C/i I have recently refoamed. With good electronics driving them, they are excellent - great across the spectrum! | |
| one large cap, or a few added up? I have heard proponents of both theories. There are some who swear by "cascading" caps such as 10uf/7uF/4uF/2uF/1uF to make 24uF. There is another camp that says that the caps should all be of the same size when paralleling them in order to avoid ... | |
| mundorf supreme caps vs m caps Haven't listened to the Mcaps, but I am a big fan of the Supremes. I replaced Auricaps in my preamp outputs with Supremes and the sound was markedly improved. More air and shimmer on the highs, less glare. | |
| Preamp Deal of the Century The increased gain comes from the constant current supply (CCS) on the 2C22 tube plate. It allows the tube to operate at maximum efficiency by ensuring a constant current regardless of load - CCS is very popular with the tube DIY crowd, and now I ... | |
| Preamp Deal of the Century Correction, the last paragraph above should read "diode bias" not "diode bypass". | |
| Preamp Deal of the Century Further Chenin Tweaking (7193/2C22)Well, I took the next step and replaced the plate resistor of the 2C22 tube with a constant current source, using an IXYS IXCP10M45S current regulator chip. A resistor in series with the chip adjusts it to whatev... | |
| Preamp Deal of the Century Mick marks them left and right becuase that'sd where they were when he tweaked the adjuustments. He has told me it is not important to keep them that way since the channels are very close.The Chard is self-biasing using a cathode resistor and capa... | |
| Great old speakers that are as good as new ones I have a pair of Snell TypeC/i that I picked up for free with rotted woofer surrounds and a detached woofer magnet. I fixed those problems and they now sound incredible! They are in my main system while I rebuild my Infinity crossovers.The best sp... | |
| Preamp Deal of the Century Update on my 7193/2C22 Chenin Modification:First of all, let me say I'm reporting on an August 2006 build Supratek Chenin preamp. I was bored with the 6SN7 sound, so I had previously modded it to run 2C22 tubes as single triodes in place of the 6S... | |
| Preamp Deal of the Century I too used Goop to secure my Solen PP filter caps when I replaced the electrolytics in my Chenin, but I also made a steel bracket that I screwed into the wooden side of the unit just in case. Do I think the Goop will come loose? No, but a little e... | |
| Capacitor log Mundorf Silver in Oil By the way, the motor run caps (of which I believe your ASC is a variety) are not really oil caps. They are Polypropylene caps which are bathed in oil inside a metal can for heat dissipation purposes. If you shake the can you can hear the oil slos... | |
| Capacitor log Mundorf Silver in Oil I am not familiar with your crossover layout, but is it possible that the inductor is causing crosstalk with other components? Are there other inductors or coils near it? Is it directly next to the high-frequency section of the crossover?You may w... | |
| Capacitor log Mundorf Silver in Oil I believe Ralph from Atmasphere was warning against using PIO caps in tube amps in another thread on Audiogon - his quote was:"Paper and Oil caps can develop electrical leakage over time that can damage other parts- this is something that most oth... | |
| Capacitor log Mundorf Silver in Oil I wouldn't use an oil cap in a tube power supply. Too hot, too high voltage - better off with the regular Mundorf Supreme there. | |
| Capacitor log Mundorf Silver in Oil Low ESR = goodHigh Ripple Current = goodASC caps are film caps; film caps are always preferable to electrolytics. And they are huge. I use Solens in the power supply of my Supratek preamp (replacing electrolytics) and they are definitely an improv... |
