| How much can a leaking storage cap degrade music? If it's leaked it's electrolyte, it no longer has it's rated capacitance(may be completely open), and the amp will have lost it's dynamics. I would replace all four of the power supply's 10,000mF caps at the same time, to avoid further problems. | |
| Running 4 speakers from a 2-channel amp Hello Mr H- The highs that pass through the inductor of a second, third or higher order filter, will be selectively shunted to ground via a cap, to increase the roll off to the woofer(and midrange, if applicable). The highs will be passed through ... | |
| Running 4 speakers from a 2-channel amp re: Series connection- Anytime components are added to a signal path, the signal is degraded. Introducing the reactance(and Back EMF) of the drivers of the systems to the signal path WILL CERTAINLY cause distortions. Whether they bother the listen... | |
| Running 4 speakers from a 2-channel amp Find a used David Hafler DH-200, DH-220 or DH-500. All can drive a two Ohm load with ease, utilizing MOS-FETs for output devices(not prone to thermal runaway). An operating 200 or 220 should be fairly inexpensive, and appear often on eBay. ie: (ht... | |
| Tweaks I guess some have never heard of Michael Faraday, and his works on electromagnetic induction? GEEZ- talk about BASIC! The magnetic field of a current carrying wire will always be perpendicular to it's length, so- YES, 45 degrees is better than par... | |
| Cary Rocket 88's Cat Eyes Do both of your Bias LEDs lite up? If not; your output tube bias is not properly adjusted(a possibilty, if the 1/2A, fast-blo B+ fuses are both good). | |
| can't find caps Check here, by selecting, "Capacitors-Film" in the box at the top of the page, then "auriCAP" at the bottom of the next. It's OK to go higher in voltage value, but not lower. You can also parallel two or more caps to equal a desired capacitance. (... | |
| maggie SMG sounds dead While the cover are off; Make certain the fuses are good, take an ohmmeter, and touch either probe to the negative speaker terminal, and the other probe to the capacitor lead on the HF panel side. If you have a reading there(around 6 Ohms and perh... | |
| Trusted tubemeisters Second the vote for Kevin Deal. His testing/burning/grading of tubes, and customer service are second to none. | |
| Anyone Tried Solen Film & Foil Teflon Capacitors? Hello Steve- 1) One of the most apparent improvements should be a cleaner high end(less glare/grain). 2) Just the standard carefulness not to overheat during soldering. 3) Yes, that IXYS FRED will work(although way overkill to replace a 1A, 800V d... | |
| Difference between Amperex 6922 pinched waist tube Here is a page that lists some of the differences in sound, between most of the Amperex 6DJ8 variants: (http://home.att.net/~chimeraone/6dj8sound.html) As mentioned by another poster; you'll never know what you like without doing the tube rolling ... | |
| Help me pick a power amp Here's what a few had to say about the Hafler DH-200, the model prior to the 220(which had more power and some other audible improvements): (http://www.audioreview.com/cat/amplification/amplifiers/hafler/dh-200/PRD_115808_1583crx.aspx) There are s... | |
| Help me pick a power amp These are readily available on ebay: (http://cgi.ebay.com/David-Hafler-Model-DH-220-stereo-power-amplifier-220_W0QQitemZ160392533002QQcmdZViewItemQQptZVintage_Electronics_R2?hash=item255823d40a), and sound much more like music than most of what's ... | |
| Anyone Tried Solen Film & Foil Teflon Capacitors? Steve- Try replacing your bridge rectifier, with a FRED rectifier block from IXYS. Low cost and very fast/soft(low noise) recovery. It's ALMOST as good as having a tube rectifier in the PS. |
