preamp for buddys computer

[karma]

hopeing i can get all the parts in this case ill be building a pre for a friends computer. it was a video booster i could not sell on e-bay. the max plate voltage on the tube is 300v so ill would like to run it at
200v if it will work. maybe a full bridge with a 200v cap and some filter not sure. if you have a idea tell me about it.

no need to drill holes for the rca's just remove the old plugs in stall rca's. works for me😉 and ill put a single volume pot on the front in the center

I found it difficult to follow your script, so I wonder how hard it is for non-native speakers on this (international) forum?

LINGO.

Hi dhaen
wonderful sound
The sound is better than my TEAC multimedia subwoofer system

nickgreek,

I'd already seen the schematic on your website, along with the internal pictures.
The power invertor for voltage step-up is interesting. How much current do you take from the computer's 12v power line?

Cheers,


Karma, sorry to hijack your thread 😉 but you must agree this is a nice idea.

Cheers,
