The biggest rails in an amp that I have my hands on is a whole +/- 80vdc. It's a mid 80s Traynor beta800 I'm fixing for a friend, claims 400w per channel at full tilt. After that I'm going to attempt to build my own 100w per channel before moving into big boy power levels, lol.
Have come across Some of Leco's posts Over on diyaudio and his stuff seems to be some very nice designs, keep up the good work... You helpto inspire people like me :) |

Here you go. Actually there is no info about the power supply voltage in the service manual but fortunately I had an opportunity and opened one amplifier on my desk.
His majesty.... the PAM 6100! ---> http://www.2shared.com/document/zdWGt0Ue/ECLER_PAM_4100-6100.html |

Sorry, i can't download from your link. It's say '' The file link that you requested is not valid. Please contact link pulisher or try to make a search''. Please upload to other host, i.e mediafire or 4shared... Thanks!!! I have a DIY amp, 95VDC per rail. Bridge topo, used 16 pairs per channel and 2KVA IE transformer per channel. Fully complementary input, based from Crest Audio CA 12. I'm used it on my DIY 15' subwoofer. |

You made it by yourself? Some pics would be nice. |

Thanks M4trix!!!
Yep! I build it by myself. Sorry, i sold it last week for a friend. I'm building another one, similar. 100VDC for each rail, used 16 pairs per channel, bridge topo with 2500 ~ 3000VA toroidal transformer. 2000W/8ohms, 0.1%THD@ full power is my destination, he he. Now, the PCB design is nearly complete.

I saw a 5kW amp that had just 2 output valves. Don't know what they were (sorry) but they were anode modulating a 10kW short wave transmitter. The modulation transformer was quite large...
But then the BBC radio 4 long wave transmitter uses a single output valve to deliver 400kW. And It's class B, because it has to be linear for amplitude modulation. |
