Wow it's been longer then I thought that i've posted something. So here we go again.
I couldn't resist to modify my used T-Bone SCT-800, I changed a few caps, stick to the same value and Voltage, and changed the Capsule, then the Tube, first I tryed it with a EH 6072. I had a feeling I lost some db after i changed the tubes so my thought was to try a EH AT7 Gold pin, I had a feeling the sound was better after I tryed a Mullard AT7 tube but this one was allready in use in my go to mic.
Ok, the Microphone functioned perfectly with the new caps, the EH 6072 or the Mullard and the New Capsule.
So i thought about to give it a proffesional paint job. I wanted to have the Main Body and the Headbasket painted first cause the price was higher then expected, and it was just an idea I had so i didn't want to spend much...
and thats where trouble starts..
I've received the parts, ok i was not lucky with the paint job but thats another story. I received the Main body and the Headbasket and main body part got a glossy type silver grey paint. I put the Microphone back together, this time with the Gold pin Tube from EH, fired it up, and I get a loud electrical hum... I can still hear my voice though the mic tho.
I switched back to the old EH 6072 and the Hum was still there.. then I tryed to fire the mic up without the Body and Headbasket..and the Electric Hum was really really Loud.. Still could hear myself but damn what causes this?
So, the Mic worked perfectly and all of sudden out of nowhere I got this crazy electrical Hum sound.. does the new paint job can cause this? something wrong with the power suply? I've not touched it at all to modify. Or did the EH AT7 Gold pin tube causes something to overload?
All I know is that this sound reminds me of something that is not well shielded.. maybe. I'm not much an electrician. Any ideas?
Regards
