| New Variac That's shocking(increasingly)!! | |
| Hearing issues and signal attenuation It seems that you would want to accentuate the tweeter level, on the weaker hearing side, to compensate for your loss, rather than the opposite. BUT: L-pads are designed to present a constant impedance to the crossover, so as not to change the cro... | |
| Cary 300SEI - tube rolling/modifications YES- Changing the amp's driver tubes will have a major impact, on it's presentation. Bottom-gettered Sylvanias(VT-231/JAN-CHS) & Ken-Rads(VT-231/JAN-CKR), from the 40's, both offer nice sound stage, depth and clarity. At least as much noticeab... | |
| Who do you trust? In God We Trust(all others pay cash) | |
| New SDS settings If the SDS was correctly set to those run voltages, and they still drop to 72V; the unit is obviously defective. That is supposed to be the lowest voltage option, for 45RPM. The 45RPM default factory value is 90V for Software Version 1.1 and is 10... | |
| Anyone try Synergistic Research PHT... "Of course, everyone's system and listening preferences (and probably bias too) will vary." You forgot aural acuity, critical listening aptitude/experience, familiarity with real instruments/vocals in a live venue and(perhaps) ear wax. There are a... | |
| What's the best EL34 amp besides 8b? Much ST-70 improvement can be realized by dropping the power supply's impedance, via added capacitance(within the rectifier's current limits). Joe Curcio helped me extensively work mine over. The tubby bass and peak compression, common to the 70, ... | |
| Who do you trust? "I trust also catalogues from major pro-audio dealers such as zzounds, sweetwater, musiciansfriend and fullcompas." He DOESN'T trust reviewers that offer their experienced opinions, based on the fact that magazines have advertisers. BUT- he DOES t... | |
| What's the best EL34 amp besides 8b? The Dynaco was introduced in 1959, and over 350,000 ST-70's had been sold when production finally ceased, making the ST-70 the most popular tube(not just EL34) power amplifier ever manufactured(though perhaps not, "the best." | |
| Concerns purchasing Vintage System? The horns in a LaScala have no surrounds. Those are the only things behind the grille. The woofers will have a treated cloth accordian surround, which cannot rot. Getting to the woofers would be more trouble than it's worth. As long as you're not ... | |
| Fuses that matter. Mr A- If you intend to reverse your internal fuses anyway: do your measurements while they are removed from the amp, to eliminate any possible issues. Place them on something non-conductive and be certain not to touch your fuses or probes during t... | |
| Quality system, make poor recordings sound better? The Dreamboat Annie masters were excellent. Nautilus did what I think was the best pressing of that album. Still my go-to for demoing Rock bass resolution(the synth & drum/Fender bass doubling on Magic Man) | |
| Fuses that matter. SORRY; I meant to include this: (http://www.scientific.net/MSF.207-209.47) | |
| Fuses that matter. There's nothing, "theoretic," about the molecular structure and grain boundaries of metals, and the effect on electrical conductivity. Just in case you're actually interested in facts: (http://scholar.google.com/scholar?q=metal+grain+boundaries+an... | |
