L'Amp: A simple SIT Amp

[juanitox]

very nice build !
i have built mine with THF51S and CCS loading at 2.1A 30V ,
much balls than my previous Sony 2SK82 amps but mucho heat too

some will say "fugly"

 

[El Reino]

Thanks

 

[Zen Mod]

Fugly! , to both of ya

(even if I see some dangling parts , here and there ........ )

 

[El Reino]

Thanks

EL Reino - it would be nice if you add exact schematic and few words more about some parts used

I see that you're using Iron in output , but can't be sure is it choke or xformer

take care to use split washers on all bolts in thermal arrangements - everything bolted to heatsink , same as on Graetz bridges

 

[El Reino]

Ok. Vfet 2SK182ES and choke 150mH 4A 0,6R. Output cap 2200uf + 3.3uf PP.

Very nice builds!
Can those amps squeeze 15-20W?

 

[Zen Mod]

don't use force , use a bigger hammer
