Hi, My Cyber Twin head died on startup yesterday. The Power amp works fine, digital (Solid State) amp models work fine, but all analog models will not produce sound. I have replaced the T1A and F2A fuses and both 12AX7's, but sitll no life.

The Eden has a thermostatically controlled fan, my first thought is to clean the fan and airways and make sure it is working properly. This relates to some heat problems on solid state stuff. If they get too hot, some shut off for protection, the fan should automatically speed up on this model to compensate. When volume is low watch the fan. Also, make sure the impedance switch is set properly. I've very rarely seen any reason to use 2ohms settings. The only way to run that is with 2 4ohm cabinets in parallel. If they are in series it would become 8ohm. Any other way will make the amp get too hot on 2 ohm setting. Most cabs are 4, 8, and 16.
First disconnect the CD head unit from the sub amp and see if the other amp works. If yes, the problem is the wires to the amp, the amp itself, or the subs/sub wiring. If no, the problem is the head unit--probably an internal short. If the other amp works with the sub amp disconnected, reconnect the sub amp to the head unit, but disconnect the sub wires from the amp. Try the CD player. If the amp goes to protect with no speaker wires attached, the amp is bad. If the amp is OK, the problem is the subs or sub wires. Hook the wires up to the amp again, but disconnect them from the speakers. Try the player again. If the amp goes to protect, the problem is the amp wiring. If not, the problem is the subs. Check the impedance of each sub using an ohmmeter to determine which amp is out of spec. Please let me know if you have questions, and thanks for using Fixya.
Not sure of how it is feeding back. Two possibilities... the reverb tank in the cabinet is no longer shock mounted. The other is your guitar can "hear" the speaker... make sure you are away from the amp. With the reverb on, the feedback stability is less than with it off so make sure your guitar is away from the amp. Acoustic guitars are more sensitive to this than solid body ones.
probably the water valve is not shutting of completly . this will flood the tray and then run over into the bucket. try // i would replace water valve . if this does not correct prob. replace the ice mker head as it time's the fill..
First make sure you have the TRIM knob positioned correctly. When playing loud the Red Led should just blink a bit so you know you're not overloading the preamp and Digital sections. The Twin Reverb Patch is a clean place to start so select that first. On this amp it's a good idea to set the MASTER to 5 and use the VOLUME control at as low a setting as you can. The GAIN control should be set under 4. You better sound crystal clear on this setting. Try turning up the volume to see how loud you can get without breaking up. It's a guitar amp so there will be some grainy distortion but it should be very light. I bet you get through this test without much trouble. After that you need to be very careful about what settings you're using since many of the presets may not mesh with your guitar pickups. You should concentrate on tweaking one highgain setting and learn about how the controls interact. The amp is so much more complicated than a 10 knob standard guitar amp. Most people need to put in some time to get a handle on it.
As far as the tubes go, typically they can get microphonic which was a problem with versions 1.1 and 1.0 of this amp so check that. Fender had a Cyber twin upgrade kit way back to fix this but if you have version 1.2 or 1.3 that's not it. Problems with this amp are typically caused by control setting more often than an electronic problem but this reponse should get you started figuring it out.
The Deluxe may have more efficient speakers....which would cause it to sound louder. Also, the EQ settings could play a part in this. If the EQ's aren't set the same there could be a noticeable difference in sound.....usually the mids can have quite an effect on overall amp volume....
