| To Pre or not to Pre? Here is my take The issue is not what is the output impedance; whether its tube or transistor. The issue is that the output impedance can vary with frequency while not at the same time having flat frequency response into a certain load impedance. IOW the output i... | |
| To Pre or not to Pre? Here is my take Even if there were engineering issues, forty years is more than enough time to solve them. Not to be a curmudgeon, but I suspect most of what is being engineered in wire and linestages are differences marketed to different tastes. This statement i... | |
| New Technics SL 1200 GAE I think it's not easy to mount different tonearm on SL 1200 GAE or SL1200 mk2. It's impossible to mount "12 tonearm and most of the "9 or "10.5 inch tonearms (except maybe jelco, sme, audiomods, dynavector, rega etc) does not fit into position ... | |
| What settings do people use with Lyra cartridges? The 100 ohm value suggests that your preamp is unhappy with RFI (Radio Frequency Interference) at its input.The 100 ohm value detunes the RF circuit caused by the tone arm interconnect cable and the inductance of the cartridge. As a consequence, t... | |
| New Technics SL 1200 GAE If you prefer just the "look" of the SL1200 mk2 over the SP10mk2 then it’s a matter of taste, but you can’t ignore the fact that SL1200mk2 is not the hi-end turntable at all, in stock condition it’s a dark sounding turntable, not interesting at... | |
| Tonearm cable recommendations If you are planning to use a LOMC cartridge and also plan to load the cartridge input on the preamp with a low resistance value then the choice of cable isn't going to be very critical. The main thing you will want to do is to look at the capacita... | |
| low power tube amp If the speaker choice is still open, consider some speakers that are more efficient (that is if you are planning to keep the amplifier). I would be on the lookout for something in the 93-96db efficiency range; generally speaking its not a good ide... | |
| Power supply hum transmitted to loudspeakers .. the faint buzz when your ears are within about 3 inches of the mid-range drivers or the tweeters is perfectly "normal". Back to the hum/woofer... I submit that at worst, you should hear a faint whisper of air when your ear is essentially ri... | |
| Preamp popping! @toddverrone Thanks for confirming my suspicion! If I recall rightly the RCAs are the 6V6s to be looking for. | |
| Power supply hum transmitted to loudspeakers With your fine OTLs and the sensitive loudspeakers you often use, can you hear any noise/hiss 1-2 ft from your loudspeakers at idle? My VAC amps and my AudioNote Kit Interstage Monoblocks both have low level buzz audible 1 ft from my KEF Ref 3'... | |
| Replacing Parasound p7, but with what? @213runnin?? I was talking about your tweeters at home not the ones in the car. Did I mistake your response? | |
| What's with BAT? No- we rejected the tube as it had a lot of the same problems as the 6922 and similar. Frame grid triodes although very linear usually don’t have good microphonic characteristics.New Sensor at the time made a pretty big deal about the tube- I thin... | |
| What's with BAT? The Russian 6H30 was actually introduced to the USA by BAT New Sensor was sending us samples two years before BAT went into business. Just FWIW. | |
| Replacing Parasound p7, but with what? In my car system using the same track I can hear more top end extension, and I guess I could chalk it up to the speaker’s frequency response or just the gains I have set for the fronts at the amp. @213runninAre your tweeters damaged? They are very... | |
| Preamp popping! You got it sorted- good work!My recommendation, if not already offered, is to look for an NOS 6V6 on eBay or the like, made by RCA, Sylvania or the like, for use in this preamp.A 6V6 arcing as you describe is a bit unusual but does suggest to me t... |
