Hi a band colleague smoked his roland 60w blues amp and every forum informs you Roland are not interested in supplying a sm power supply or diagram.

The fuse is blown
33 ohms resistor smoked
2 x irf 740s bought to replace
The other two are [on]
Aff 51 U1620rg kak Does anyone have an alternative number that is available please

Thank you Pips

 

Is it really worth it to try to repair this thing ?

Yes most definitely..
It's a good sounding amp and better being repaired than in a land fill.
Roland seem to have adopted a throw away policy and that will turn away many potential buyers.
I have all the parts other than two mosfets which I'm struggling to find. Hopefully someone will respond with the information I'm after
Thank you

 

Do You have legible part-numbers on the original FET packages ?
If not, it's somewhat of a crap-shoot.

It's the Speaker(s) and the Cabinet that "sound-good", not the Amp.
( and "sounds-good" is being extremely generous )
