| Difference between today and yesterday. Was it Duke Ellington who said"If it sounds good, it is good".Some truth there.. | |
| New Product......Intelligent Box There ought to be a law. | |
| Tuning a back loaded horn What is a "back loaded horn" ? Would that be like a Klipshorn? If so, no fill is used. | |
| sub distortion? In a cone driver distortion increases rapidly as the excursion of the cone (travel in and out) increases. Drivers made for subwoofer use generally have a large range of excursion, but it's obvious by looking at a busy subwoofer that the full range... | |
| 400W amp under $2000 CarverPro ZR1600. 300 wpc @ 8 ohms, 600 wpc @ 4 ohms.Less than $1000. (Check the web). Sounds good. | |
| House speaker wires advise? You need to use wire that meets building code for in-wall use. I have used Carol E1062.12 wire, and I think it is good, Parts Express.com. Item 100-742. It is AWG12. 500 feet costs $213, but 1000ft is on sale for $299. | |
| EQ before Preamp? Mordante...You're correct that the best capacitor is no capacitor (at least in the signal path). My Kenwood LO7M power amps (from the early 80's) are direct coupled input to output, and are flat to DC. You can really hear the benefits, particularl... | |
| EQ before Preamp? Rodman99999...You ask..."Is there a way around the effects of an EMP bomb yet?" Yes, but if I told you all the details I would have to kill you :-)Actually there are multiple techniques; some obvious like shielding, but lead is heavy (bad) so we u... | |
| What are those extra tube inputs for? The picture reminds me that there are two of these sockets. That's because although this power amp is stereo, most preamps, including Dyna Kit's were monophonic, so you had to use two. Having two volume controls was a pain. I modified two Heathkit... | |
| Review: Bose 201 Series V As described in another thread I have taken a flyer on Bose 901s for the large high ceiling swimming pool room that I have recently built, and the results are well beyond expectations. I would not like these speakers in the typical listening room.... | |
| EQ before Preamp? Rodman99999...Once upon a time Mil Spec components were superior. Perhaps you are unaware that military equipment, at least that I am familiar with, today strives to use only commercial design parts which, because of the volume of production are o... | |
| What are those extra tube inputs for? Those connectors on the side of the chassis are for a plug with wire from the original Dyna Kit preamp that had no power supply. It drew the power it needed (not much) from the power amp. | |
| Balanced vs. unbalanced By the way, the noise immunity of balanced lines can be achieved using active circuitry only in the receiving end of the connection. The HI wire of the balanced connection carries the single-ended signal. The LO wire is simply connected to the sin... | |
| 6L6 or variant Kt-88....I just looked at those amps. They get to 20 watts, instead of the usual 10 watts, by using four 6V6 output tubes. I am sure that performance is limited by the small audio output transformer. A substitute would not fit on the chassis unles... | |
| EQ before Preamp? Rodman99999 and Joeylawn36111...Just for accuracy...My work was on missile guidance systems (which just happened to be launched from subs) and my audio electronics experience goes back to about 1955. I didn't make audio my profession because my fa... |
