Hi there, Imagine a room the size of an average church, same height of ceiling but all in wood with a much better sound. A stage on which there is an incredible sound when playing, My question: what would be the best way to record the sound of the room to get a maximum of drums ambient sound with a ...

I recaped them all, so that is not the cause of muted higher frequencies. After some research these are known signs of old and tired tubes. I have bought new ones so I will wait and see. BTW, if any of you has experience with tubes and advises me on what to buy as ECC82 and ECC83 for my preamp that ...

Hi, I have a modified 351 Ampex. The output sound lacks clarity in higher frequency. here come two samples: a guitar on a tlaudio http://idoia.com/electrical/tla-1.wav same on the ampex/ http://idoia.com/electrical/ampex-1.wav Can this be caused by bad tubes ? Thanks for your anwer. Alex

as for the mic, a coles would be my favorite.

Hi Greg,
Did you have a chance to look at my post right above rambi10's one.
I still have not touched them since I posted this thread and would like to know if my questions make sense.
Thanks
Alex

Maybe one question that could really help me, on your schematics, both 9 pin of V5 and V4 are connected together with the GN/Y of the main transformer. Am I reading well ? Least but not last, on the same part of the board, pin 5 of V5 is connected to pin 4 of V4 but on the original board, both pin 5...

Hi greg, I have put another transformer before the main one so that the current is transform into 110 before. The only thing is that the transformer should at least provide 100W unless the ampex won't power up. I have done two of this units and have for both of them the same problem: Looking at your...

21B are the capsule of the mic.
They are omni and have been made right before the 21D.

DMM, ...of course...

Klaus Heyne's mic lab: url ?

Well I did both types of measurements as the schematics also provide voltages without load. And yes 10% is the maximum of excess of voltages that I have.
A DMM ? What is it ?
It may also be useful (maybe not) to precise that my caps are 21B (closed and with holes)
