| tube amplifier auto bias- accurate? I wonder if Macs were the first ones to implement autobias successful in their vintage gears like the MC240s. | |
| Mac MC240 1. For the output tubes, the one in front of the left transformer is left channel ( The center transformer is power transformer) the vise versa. V8 and V9 are left and V10 and V11 are right.Since MC240 are auto-bias, it is recommend that match qua... | |
| Audionote Soro SE, or cheaper single-ended? IMHO, sure 90db will make sound with 3.5 Watt but lack of lower frequency response. Even for 93~94 db, 3.5 Watt can't produce the bass right. Lack of punch and dynamic.If you have an active sub to go with it then it will work fine. | |
| Best amplifier for Tannoy GRF Memory HE The Jensen CX120 16 ohm alinco from the late 50s and early 60s. The CX225 has slightly bigger alnico and one inch deeper but not sure how it would sound.Here is a photo of my speakershttp://mysite.verizon.net/vze7qf7h/sitebuildercontent/sitebuilde... | |
| Best amplifier for Tannoy GRF Memory HE Rdr4b, Couldn't agree with you more. I also visit Akihabara back in 1998 and was so impressed by the Tannoys. I wasn't into vintage gear then so I don't recall which model. I now also own a vintage pair of Jensen coxials with my own GRF type of ca... | |
| Mac MC240 The stereo vintage Mac amps are much more desirable. Both transformer's winding had to have same number of turns in order to make the match pair.Since I don't have MC40 ( only heard the MC30s), I can't tell you how it sound. It is older than the M... | |
| Mac MC240 Yes the 7027A are direct replacement in the case of MC240.Telefunken 12AU7s are more smooth and refined but less dynamic and punchy when compared to Amperex 12AU7s. | |
| Mac MC240 We have 4 MC240s among our friends. The bugle boy nor Amperex (both made in Holland) makes no difference. If you want the best 12AU7s then go with Amperex 7316 tubes.Cleaner without loosing the nice sounding. Even the Telefunken 12AU7s are nice to... | |
| Mac MC240 1. Hi/Lo voltage 115/117 switch2. Mullard 12AX7/ Amperex 12AU7/ RCA 12BH7 bk plate/ US brand 7027A instead of 6L6GC not Russian tubes3. Home brew pure silver cable/ NBS Master speaker cable | |
| WBT Topline or Nextgen RCAs for Pass X250 I would go with topline 201E . pure 5N copper vs 99% copper alloy on the Nextgen.One piece construction which is almost unbreakable ( vs the cheap plastic Nextgen.)Eddie current effect on female connector? not sure if it even get a good contact wh... | |
| Help with what's wrong with my 300b amp? If the 300Bs didn't lit up, there is something wrong with the heater current source. Turn on the amp without the 300Bs and driver tube. Measure the voltage accross the heater current ( pin 1 and 4 )You should get 5V for each tube. If no voltage th... | |
| can anyone help me?? You also did not specify speaker size, room size and amplication used. On top of that, sources and cables are just as important too. | |
| Goodmans Triaxiom 212c scratchy sound Like Twl said, you probably need to re-align the voice coil so that it doesn't touch the side (that's what made it sound scratchy especially at higher volume.) | |
| Older PURE CLASS-A Amplifiers The Platinum Reference I is the biggest chanllenge to power amps. I have yet to find anything that make it sound acceptable to my ears.I have matched it with about a dozen amps 5 years ago (from $$$$ SS amps to tube amps )and gave up at the end. N... |
