| REL owners, how many clicks on your gain and crossover FWIW, with my stereo pair of S/510’s the settings in my 28’x15’x8’ room are: Five clicks from 20 hz on the crossover and 12 clicks clockwise on the high level input for use with a pair of Thiel 3.6 speakers; 3 o’clock in the crossover and the sa... | |
| Blowing Fuses. Dennis Had Inspire 300B SET Turn on the amp without the tubes installed. If the fuse blows send the amp in for repair. If not, then there's a 99% chance it's a bad tube. | |
| Am I reaching the max power / amplitude of my Rotel RB-951 power amp? I looked at the specs for your amp... the high level setting has an input sensitivity of 775mV. The Kenwood receiver specs show a tuner output of 160mV. That's why the amp is not playing loud, the tuner's max output is -14dB lower than the voltage... | |
| Am I reaching the max power / amplitude of my Rotel RB-951 power amp? Does the loudness vary in proportion to turning of the level screws? | |
| Volume Problem Trouble Shooting Ideas? If you have a digital multi-meter check the resistance from end to end of the cable. It should read at the lowest end of the scale around 0.1 ohms. Anything more and the cable is eating up the signal. The resistance will read more if the connector... | |
| help me identify this amplifier Very likely not a name brand but a home built. The giveaway is the wooden blocks glued to the sides and front -- they are used to hold the bottom cover screws. | |
| Floating ground in the apt. Building You have a romex spool with the ground wire too short? What does this have to do with the wiring already in the wall? Unless... Did you take that romex spool to your new apartment and then connected to a new outlet you installed and then ran the ... | |
| How long does it take your tube amp to warm up? From my experience, it doesn't matter how long you let the tubes warm up. The amp won't sound its best until after 15 minutes of signal has passed through it. Ten minutes of idle is all it takes for a KT150 (the highest power dissipating tube out ... | |
| Hearing other appliances in dedicated line My guess would be arcing. Those appliances may be on one circuit and there is a loose wire connection at either a receptacle or the branch circuit breaker. Call an electrician and describe the problem. | |
| Checking for crossover and driver issues That DC offset circuit itself could be at fault. Amplifiers cannot be diagnosed over the phone with non-tech customers. Don't waste your time troubleshooting, send it for warranty repair. Just to be sure, check to see if the wall receptacle is op... | |
| 10 gauge power cord. Too much power for tube amp? Power cord has nothing to do with the amp shutting down. The protection circuitry is kicking in. Don’t know how it’s wired but it usually senses overcurrent at the output stage. This can be caused by a failing power tube, a total loss of bias volt... | |
| Power Cables - Third Party or OEM It's not an engineering discussion, it's a marketing discussion. Of course an OEM will recommend their power cords and not the competition's. The oldest marketing pull is trying to convince consumers that using one brand's product (whether it's re... | |
| Can you touch the tubes? If you look through tube manuals under Installation and Application the only things stated are the socket pin counts and whether or not the tube can be mounted in any position. Since "touching the glass" is not stated (or "do not touch if they glo... | |
| McIntosh C28 transistor subs Not always. The biggest problem you run into is the surrounding circuits are tuned for the spec'd transistor (or vice versa) and a substitute that may seem the same may not work in that circuit. Trust your tech on this one -- he doesn't want to wo... | |
| Tracking down a hum. Go with the tubes first. Always keep a spare set, replace when you suspect a problem, if that fixes the problem throw the old tubes away and buy a new spare set. What you are describing, I would bet, is the 6SN7 heaters are not powering up togeth... |
