just another gainclone

[karma]

well i needed somthing to do so i tryed making another one with a
33 volt transformer and some caps on the power supply.
wow this amp is loud but no heat . no caboom yet

33v + 33v 2.8amp transformer kinda overkill lol


and the meters are working

later

looks good no problems. and i dont get the dredid hum when there no input. dead silent

i made a few changes to the original smatic. i will post it when i take it apart.

That must be a very good sounding transformer you have there ;D

That is the smallest heatsink I guess. No heat? You must use it
to feed Sony bookshelf speaker

The green caps, are they supply pins bypass? What brand? The
bigger ones, they look like 1000uF/50V Black Gate. I always try
to use the cap as close as possible to the pin (no long cable).
OK, you have those green caps Sound silly, but the 1000/50
seems to not like working with other caps. In my preamp, adding
another 1000/25 Pureism led to horrible sound. Even the 47uF
Black Gate N must leave the PCB and replaced with 5nF SilMic,
another silly judgement. Blame my ears.

beautifulI have seen some white block things,is it film caps?

the white things are resisters to step down the power for the lights im to cheep to make a voltage regulater.

but i may go with white led's the light's make a lot of heat

the sound is great punchy at high volumes.
i made changes but there out of view under the boards
i need to right down everything i did so i can make more

i made up a little board i found here. thay dont jump around like the cheap ones. thay hover at the right voltage from the amp
i set it up with a voltage meter and a resister. its allmost right
maybe off by a volt

heres how it is set up. kinda sad looking
i was just playing around with a chip and ran into it. feel free to pic it apart.what works for me may not work for you

hay but it works so im not touching it

after the transformer and rectitier and the 2 power caps the amp is runing on 41v

the cap on the output turn it around its backwards
