| Advice on Repairs for Audio Research VT100 Mk II There are 8 power tube 100 ohm 5% 3 watt screen resistors. (Part # 43100208) ARC uses the resistors as fuses. The wattage value should never be increased. There are 8 power tube plate 1 ohm 2 watt 5% BLUE LINE resistors. (Part #43100004.) https:... | |
| Advice on Repairs for Audio Research VT100 Mk II @edward78 The VT100 MK II first came out in 1998 though 2000, (maybe through the spring of 2001). The amp is at least 21 years old. I am surprised the Tech that gave you the price for the repairs didn’t mention that. How about the electrolyti... | |
| Advice on Repairs for Audio Research VT100 Mk II @edward78 said: I’m fine with the price of the resistors, 6550 tubes, and labour but the price for the 6992 tubes seems too high. On the JJ Tubes website, these tubes sell for about EUR 20 a piece and they do not even offer matched sets of 6992.... | |
| Another dedicated circuit question Different potentials always try to equalize to the same potential thus there will be current flowing between the two (or more). It will always use the path of least resistance. The current will take any path that is provided... As for using mo... | |
| Another dedicated circuit question @immatthewj said: I was ASSUMING that a 20A breaker should not only be in front of, at minimum, 12 gauge wire, but also a 20A breaker. That is correct. The breaker determines the ampere rating of the circuit. 20A breaker, 20 amp branch circuit... | |
| Another dedicated circuit question @immatthewj , on page 3 of the instruction manual (pdf) is where it says to connect it to a 15A outlet. "4. The PST-8 should only be connected to a 120 VAC, 60Hz, 15 amp grounded electrical outlet." "Connected to a 120V 60Hz 15 amp grounded ... | |
| Another dedicated circuit question @immatthewj I found out that three dedicated lines was another mistake I made. Not really... If the correct type of branch circuit wiring is used, and the correct method of installing the branch circuit wiring is used. I have two dedicated ... | |
| FUSE Question...Very Confused Please Help ! @ieales The amplifier is designed in Germany. EU has 230V AC mains power. As stated the amplifier is made to be fed by 230V or 110V. The odd thing, at least to me, is the 110V mains feed. Not sure how the designer arrived at 110/230V. Usually ... | |
| FUSE Question...Very Confused Please Help ! Owner manual specs: 500VA Max power consumption. 500VA / 110V = 4.55A. The designer of the amp only bumped the fuse up 110%. 4.55A X 110% = 5A. A 5A slow blow fuse seems a little tight to me for the amplifier... 500VA / 230V = 2.18A X 110% = 2.... | |
| FUSE Question...Very Confused Please Help ! @rocky1313 From page 6 of owner manual: V S – Mains Voltage Switch (12) VOLTAGE SELECTOR The Penta 5.1 amplifier can be used in all countries and is good both for 110/115 and 220/230 V. Before the first operation, please make sure that ... | |
| FUSE Question...Very Confused Please Help ! @rocky1313 Use a 250V rated fuse per the fuse holder as stated. 250V/5A #2. AC 110: S5A... 110 is the AC Line voltage setting for the Amp when the wall outlet mains voltage is 110V - 120V. (S5A 250V fuse.) Are you sure the fuse is a S5A? Using... | |
| Ground voltage!! This thread is excellent at demonstrting how clueless this forum is about electricity. It will be hard for the OP to figure out what to do based on the various answers here. It appears you have properly measured 80 volts ground to neutral. ... | |
| Ground voltage!! bushikai OP 10 posts 11-04-2022 at 04:03pm Hello, Sorry for the confusion is 80 volts earth and neutral. @bushikai Just a guess your multimeter was set on auto scale and you read 80 mV (millivolts). Not 80 volts. Look to... | |
| Isolated ground in dedicated room/new construction? Would it present as sounding grainy /static? I figured the recordings that have some grain were from the recording. @ronboco Possibly. For a test, turn off the circuit that feeds the dimmers and LED lights at the electrical panel. The... | |
| Isolated ground in dedicated room/new construction? @ronboco Yes, and that includes the branch circuit wiring from the load side of the switch to light fixture(s). When can lights are used in a ceiling it can be a challenge to route the new dedicated branch circuit cable(s) from the parallel runn... |
