| ARC VT100 with KT-120 tubes ? Both the Ref210 and Ref610 require changes to one of the regulated power supplies in those two amps. I will probably be able to update the Ref210 at my office, the Ref610 on the other hand requires a more extensive update and therefore Ref610's wi... | |
| ARC VT100 with KT-120 tubes ? Bifwynne, I will be getting in a VS-115 with KT-120's for service. I will let you know what the power output is once the unit has been gone through. | |
| audio Research REF 110 and KT 120 tubes Tlg...ARC is NOT using the KT-120 in any power supply in any of their products. 6550 only...I have KT-120's | |
| 12AX7 tubes for Music Reference RM-10 I have an AVO tube tester in my shop if you need to check some tubes. I've also had very good luck with JJ E83CC/12AX7 tubes if you were looking for a particular brand of tube. | |
| audio Research REF 110 and KT 120 tubes BTW I just retubed a VS60 with KT-120's. Awesome. In case someone was wondering if you can put KT-120's in a VS60. You can. | |
| harman kardon citation 16 amp????? Make sure they clean and repack the output devices. Heat sink paste tends to dry out and crumble and no longer acts as a good thermal conductor. | |
| Bridge Robertson 4010 Question? BTW Robertson products were designed by John Iverson. I used to work for the company responsible for assembling Electro Research Speakers. He was a very interesting man to say the least. Robertson amps and preamps were assembled in Asia I believe.... | |
| Levinson 331 humming followup... It's odd that Philips caps would be leaking. I have used many of them in the past for service replacement and found them to be very good,with very low series resistance which is important in a good filter capacitor. It is possible that those caps ... | |
| any good 110v-220v voltage converters?? Albert you pronounce it cayble??? It's Gary from L.A., and I agree with Mr. Porter. Using any kind of step up/down transformer can create a sonic nightmare. Any chance that amplifier has a multiple tap primary on the power transformers? That means... | |
| harman kardon citation 16 amp????? Sorry for the misspelling. His name is Matti Otala. | |
| harman kardon citation 16 amp????? Very good amp. BTW the Citation 12 was the first amp to use a differential input stage. I believe both the 12 and the 16 were designed by Matty Otala. A very gifted designer in the day. I don't know if he is still designing. The Citation 12 was th... | |
| audio research Well I am in error. After looking up the circuit diagrams the SP-8 does not have a tube rectifier, it has a tube voltage regulator which I still prefer, easier on the tubes. Sorry for the confusion. This is what happens when you don't check your f... | |
| audio research I would not go with the SP-9 unless it was a MKIII version. The SP-9 had issues with crosstalk and manifests itself as a lack of space between instruments, as well as a somewhat gray back-ground instead of black. Old f.e.t technology. Instead I wo... | |
| How to restart tube amp and pre in boxes for 2yrs Well that works. lol | |
| How to restart tube amp and pre in boxes for 2yrs Larryi I've been doing that kind of work for 25 yrs. Actually a cap will give you warning signs. At low voltage they can heat up and/or sizzle or tic from arcing. That's why you run the amp up slowly. Never bring an amp with caps that make noises ... |
