fun little amp. Tiny terror pre on a 4x6au6 pp pa.
« on: December 11, 2011, 01:39:29 am »
the title might say it all i guess. Disatisfied with my second 6au6 venture I decided to change the preamp to a tiny terror type. LTPI PPIMV and 4 6au6 make the  push pull power amp. 269ex power trans and a 125c output. I was kinda surprised at the volume. Its a little louder in this configuration and the power tubes sound much more convincing as pentodes. I still have to implement the tone control thats post PI. It sounds pretty raw without it though. will post vid clips and schematic as soon as I can. Cheers!

Very interested in a schematic and maybe the layout too

Hey guys, sorry about the lag, Im scrappin this one as I cant get it to sound right. Maybe another amp project with these. I havent put instructional vids on yet either. I finaly got busy at work so ive been focused on that and gigs a lot. I am still building though. starting a different thread for new project you may be interested in using 269ex and 2 6v6 in pp config. Can we delete this thread or whatever?  Cheers, Zambo
