| Never Use HiFi-Exquis - Worst Merchant Ever! ".....blaming the Chinese for the pandemic without citing any credible proof is just wrong." Cranial-Rectal Inversion (obviously)! | |
| Compression Horns for Far field listening You’ll need an inductor at least (for a 6db/oct slope), to block the highs from the 8" driver. http://www.apicsllc.com/apics/Misc/filter1.html Choose parts and a slope, via this, for the horn (1uF @ 8 Ohms = 17,000 Hz @6db/oct): ... | |
| Tube Dealers 2021 Brent Jessee Recording is my go-to, for rare, NOS, 6SN7 Octals. I've gotten some of my very best NOS, nine-pin miniatures (especially, my Siemens), from this seller, in Germany: https://www.ebay.com/usr/audiotubes_de?_trksid=p2053788.m154... | |

| Warning: China-Hifi-Audio.com ZERO surprise (even less sympathy)! | |
| Dahlquist DQ10 issues "...so I tested by listening until I started to hear the failure...". Knowing how that, "failure" sounds would be most advantageous, to anyone attempting a diagnosis. ie: A dead, complet... | |
| Dahlquist DQ10 issues btw: If the system’s still putting out some sound, but at (seemingly) much lower levels: try cleaning the treble level control (and again, the tweeter fuse holder). When the upper freqs are missing, everything sounds way off. I suppose I... | |
| Dahlquist DQ10 issues Your DQ-10 pair was manufactured with metalized Mylar capacitors. Film caps don’t age, dry out or leak as do aluminum electrolytics. Unless a resistor burns: they don’t typically go bad either. If there were an issue with the crossover... | |
| Cable Elevators Why would those with experience have anything to concede, to those with theories? Especially: given the plethora of variables, in this hobby. | |
| Phase Linear 700 & 400 series II "Hand an idiot the keys to a Ferrari and watch what happens." Based on the plethora of 700/400s requiring repair (way back then): an atypical number of, "idiots" must have owned them. To th... | |
| what is "B" stock Oldest dead thread resurrection, in quite some time. Not one of the posters has been AudiogoN-active in 20 years. KUDOS! | |
| How old are you? WELL: they discontinued my blood type...... | |
| Variac or not? "Can you explain why lowering supply voltage (variac) would burn out resistor in series?" Just thinking there may be a corollary, here: An AC motor, connected to too long of an insufficient gauge wire/cord and the attendant volt... | |
| Preamp sending amp into protect Then again: some amps have coupling caps, at their inputs. ie: The early Haflers had a, "C1", for blocking DC, on the driver board's input. Perhaps a bad one, on the left (if applicable)? | |
| Preamp sending amp into protect Some preamps have (coupling) capacitors in series with their outputs, to block DC from the power amp. You may have a bad one, in that channel. Try swapping the outputs of the pre and see if the problem follows (L to R). If so: at leas... |
