I use TinyCad (it's free) on my PC but would like to know what would work best on my iPad.

I use Circuitmaker2000 it has tube models in it.
For everything else I use DipTrace, Designspark and Express PCB and SCH.

I have use TinyCad as well to draw with, it is a great little package!!

I also use TinyCAD. Double check the pinouts though. The version I got a few years ago had wrong pin numbers for dual triodes!

I also briefly experimented with KiCAD. I need to go back and try it again. I was used to TinyCAD at the time. I've used Cadence OrCAD Capture at work for 15 years but obviously that's not very cost effective for us to use at home.

Microsoft Visio has tube symbols, resistors and other implements of schematic making. Not the most user friendly stuff though.

Cadsoft Eagle has a downloadable tube library. I use it for making schematics and PC boards, but they have decided to price it out of my range, so I am looking for a good alternative. Design Spark (FREE!!!!) might be it.

Default Thanks Guys

Could not find my copy of visio know I hav one but....
so I went with Express SCH, was at a loss as where to start but jazbo put me onta sum .SCH files and one of em was 5E3 based so i was half way there just had to re organize it.

anyway this is how I think I built the last amp will go back an check all the resistances and capacitance's tomorrow night I know sum are not quite right as I didn't hav all these ones so used what ever i had that was closest.

V1-2 cathode value is definitely off. ECC802 has very low gain to begin with, so you may want to bypass the cathodes - any reason you are using it for the preamp? Also, the schematic looks kinda funny with the preamp tubes flipped upside down, no big deal though...

Oops, your quite right that should read 2k not 100k. If ya spot any other stuff ups let me know lol.

I had a 12ax7 in the pre to start with but it feed bak too much. the 802 is just about right tho and there is plenty of gain here to throw away lol. when my Weber harp speakers arrive (which dont hav the same High end response) I may try the 12ax7 again. or an ECC803 (supposed to hav a creamier sound.)

Thanks again for your help.
