WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Another thing I found on my older HD TV's 24/22"" from 2005/ 2008 is that using 3 RCA cables for the component video to my SAT rec. gave a noticeably better picture than the HDMI cable. Maybe newer TV's are better that way, but if you can give that a try also!
Does anyone know how long you can run RCA cables for audio?
The TV antenna goes into a HD Homerun ethernet tuner which is plugged into the router. All computers in the house and the laptops get TV through the router. The TV in the living room has it's own computer. The computer has a 24/96 sound card that feeds a 125 WPC tube amp which goes into 15 inch OB speakers with 96 db sensitivity.
The only application that requires anything above a Core i3 is Overlouds TH2, a guitar amp processor and simulator. Plug the guitar into the PC, dial up your favorite vintage amp and stack, and really annoy the neighbors with 250 watts. Any mid range video card can run two TV's in 1080 HD via HDMI.
The PC can DVR the usual crud that flows from network TV. It can also play the HD videos on Youtube. The tube amp can reproduce the live Metallica concert in HD with realistic volume levels....except for the pyro.
The audio and video from the cable box is heavilly compressed by Comcast and doesn't compare to OTA quality. Ditto the audio outs from a 5 year old Sony TV.
My Tube amp is the center of my entertainment system.
My Blu ray and Xbox go to My Marantz SS for a pre amp then to my ST-35 tube amp. Smooths out the digital. When I had cable, I ran it to my SS vintage receivers.
My current system sounds best when I use the DIY tube pre amps I'm trying to create- done on a solderless breadboard....so I can only imagine what a complete one would sound like.
I'll have to buy a flat screen for movies. I don't have very much time to watch television. I have cable only internet purposes and sometime I don't get much of that because of the music world demands.
which reminds me, I have to set up my tracking appointments for next week.
It uses input transformers, so i do not have any hum issues.
You should try a DI box for each channel, if your amp is not balanced.
This is because broadcast-provider boxes use a different earth-line than your in house earth-line..
