| SB Acoustics 12” SB34NRXL75-8 You don't mention anything about a midrange or tweeter, without which, there's no need of a crossover and an unsatisfying result would be a given . Any advise, regarding cabinet sizes, compatible components and crossovers, can be gotten from th... | |
| Why so few speakers with Passive Radiators? Legend- With a little research, you’ll find that both a properly designed/implemented radiator, and the mass of air in a vent, act as resonators and reinforce the system's TUNED bass response. Below the tuning point, yes- cancellation occurs(and ... | |

| Why so few speakers with Passive Radiators? Systems utilizing passive radiators ARE, "vented" systems. The Thiele-Small parameters and calculations, are identical for both. Only the application(vent or radiator) of the results(mass of port air/size and weight of the radiator), varies. https... | |
| Wow! Vintage HiFi magazines. These guys offer reprints, of some of my favorite old rags(ie: Glass Audio, Speaker Builder, etc) http://www.audioxpress.com/tags/Glass-Audio | |
| Tube or Trasistor I’d like to have more info on the amps, as well. Input tubes(ie: phase splitter and driver) can make a major difference in your presentation. Especially, the thin, uninvolving presentation, that will result from tubes at the end of their lifespan.... | |
| A "primer" on soldering... Good article, George. I’ve always used small alligator clips, as heat-sinks, on the leads of whatever I’m soldering. Can’t hurt, to be safe. I also like using solders with low melting points, and silver content. My faves: https://www.parts-express... | |
| Recapping your amp A timing belt won’t degrade your engine’s performance, before it fails(completely). The point of my references was, that(electrolytic) capacitors do. Of course: to many, "...still working...", is good enough. Do you replace your racing tires, AFTE... | |
| Recapping your amp Aluminum electrolytics can even go bad(via dielectric polarization), given enough time, on the shelf and unused(http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.823.6133&rep=rep1&type=pdf). Of course, heat and cycling, also take th... | |
| Speaker boxes. To rebuild or not to rebuild @roxy54 - I would have mentioned that, but was trying to be kind(iow: +1). | |
| Speaker boxes. To rebuild or not to rebuild Measure the mounting surfaces, and contact these guys: https://www.madisoundspeakerstore.com/ They can provide drivers, crossovers and any components necessary(of various qualities/prices), to complete your system. | |
| Tube tester recommendation! Testers also require occasional recalibration, which will probably be necessary, if you buy one via eBay, craigslist, etc. Another option for having them tested, should you choose not to spring for a tester: http://tctubes.com/tube-testing-servic... | |
| Triggering mono blocks without trigger capability Good idea(easier than DIY), but- be certain your preamp’s 12V trigger, can provide a constant 100mA, if you go for the Niles. The alternative(if not) is a 12V/100mA (or better) , DC adapter(wall wart), that would plug into your preamp’s 125V swi... | |
| Triggering mono blocks without trigger capability Where there’s a will, there’s a way(though, perhaps, NOT the best for audio apps). If I wanted to trigger a power source, I’d find a 12V coiled relay, with whatever voltage/amperage-rated contacts needed and wire up a distribution box(outlets). Po... | |
| What solution to clean silver and gold contacts? BTW: Silver WILL form an oxide layer, as long as the, "ambient conditions" are below 195 degrees Celsius(almost twice boiling), and - the atmosphere contains Oxygen: https://study.com/academy/lesson/silver-oxide-formula-decomposition-formation.html |
