Hello Chaps

Just a few words of introduction. I have been reading this forum for some time and thought it about time I should join.

My music tastes are Jazz, Classical and especially Opera. I am an avid constructor of thermionic audio amplification devices of various ilk. Over the last twenty years or so I have built valve amplifiers in both push pull and single ended designs using El34's, 300B's, 2A3's and 45's, phono and line stages using ECC83's, 76's 6SN7's and 5687's etc.

I listen to vinyl and digital through various setups with a choice of ESL57's, Lowther DX4 based horns and Living Voice OBX R2's.

Current set up is:-

Vinyl: Palmer 2.5 TT, Jelco 750L tone arm, Koetsu Black Goldline, DIY JFET head amp, DIY ECC83 valve phono stage.

Digital: Vortexbox 1.9, Logitech Transporter.

Pre-amp: DIY TVC with Sowter TVC transformers.

Power amp: DIY mono block push pull EL34.

Speakers: LV OBX R2

Thanks for reading!

Welcome, Martin, from another one. You have some unusual kit there - not to mention the device on your head. Does that help the imaging?

Hi Martin,
Sounds like you'll fit right in (pun intended). There are quite a few on here who appreciate what valves bring to the music experience, me included.

Another '57 user as well :thumbsup: Look forward to more info and the pics.

:cool: Alan
