| New KT150 tubes? There you go... | |
| New KT150 tubes? Just to be fair, I only recommend and use tubes from ARC. They are 'properly' matched and tested for at least 24 hrs at RATED VOLTAGES prior to being shipped. ARC products are too expensive to play Russian roulette with. | |
| Audio Research D70 mark1 + schematic CDE's are fine provided the meet the capacitance and voltage requirements. | |
| Audio Research D70 mark1 + schematic V6-7 plates should have 240Vdc on them. Measure across each resistor to make sure they are 64Kohms. Do they say 64Kohms on them? I believe they were black Dale wirewound resistors. They should be the same on both channels. Hopefully someone didn't... | |
| New KT150 tubes? Let me clarify, Alon in now Nola Speaker. KT-150's are still in life test with over 4,000 hrs on one set of tubes. This is good news. I'm sure they will be a drop in replacement for ARC amps that came from the factory with KT-120's. That being sai... | |
| VTL Verses ARC, which is better? From a service perspective I would opt for the ARC. | |
| Audio Research D70 mark1 + schematic The voltage on the collector of TIP41 is 335Vdc. On the emitter of the TIP41 it's 327Vdc. They may vary a bit but the 8Vdc difference voltage should be the same. If it isn't, the buffer has issues. If you are unfamiliar with measuring high voltage... | |
| New KT150 tubes? No mods other than the typical bias adjustment with new tubes. | |
| Heads-Up: ARC introducing new G Series I believe the G series would come under the heading of audio jewelry, a segment opened by Dan D'agostino. The visual/mechanical design of the G series was designed by Italian designers. The circuits were designed at ARC. I'm sure this was a market... | |
| Audio Research D70 mark1 + schematic I believe that unit shares a similar power supply with the D115 in which case there are indeed solid state devices in the voltage buffer circuit unless somebody removed them. It's important that they be functioning properly or the output of the am... | |
| New KT150 tubes? I was at The Show in Newport Beach this weekend and walked into the Alon Speakers room hosted by their designer Carl Marchisotto. Low and behold he was running a ARC Ref 75 with KT150's in it. He said, and these were his words, the differences bet... | |
| New KT150 tubes? I don't have an answer for you. I will have to differ to ARC and wait, but I am getting impatient. I will ask again next week. | |
| New KT150 tubes? I have no idea.. I will have more info after next weekend after the hi-fi show in Newport. | |
| New KT150 tubes? I believe the pic on the web site is the G integrated amplifier. | |
| New KT150 tubes? Haven't the foggiest idea. They normally don't post pics of products that are not available yet. The G series will be very expensive, that's for sure! |
