Hi, so this K150 has a tag on the back that identifies it as being made for 220 volts?I need a reply before I get into anythings to check circuit wise.
The front panel switches have no replacements, but if you open the amp up and remove its lid to get into it you will see that the black round shank of the switch is what has broken letting it be pushed back from its mounting section, what I do with all mine that have busted and even the ones that have not, is to take some nylon small size cable ties(not too small, but small enough to work) and tie one around each side of each switch to keep it pulled up to its mount,I fixed my first K250 this way back in 78 and have yet to have it fail!
As far as the covering goes,sure recover it in what ever you want, but save the old tuck-n-roll for a pattern in case you ever want to get it recoverd as the shop who does the work will need it.
If you gig and move the amp alot and do not have a cover for it, I have found that the gray type carpet covering shows the results of abuse far less than tolex covering.
I can not find any info on your mixer but, if its stereo than its output would be 130 watts RMS a side, not per channel which will be more than your speakers can take,in this case I would not turn up the master volume more than 3/4. If the output tag on the back of the mixer says 8 ohms and your speakers say 8 ohms you will be ok. If the mixer is not stereo and is rated for a 8 ohm load and you plug both your speakers in which would be a 4 ohm load I would back off to a little more than 50% of that master volume setting.
each channel may have a gain control and a clip light,the proper way to set each mic is to bring each channel volume to the zero DB line(I think this mixer has sliders for channel volumes)set all the EQ or tone controls to the middle position and then open up the gain control while singing or taking as loud as the level that will ever be used and look for the clip light to come on, when it does back down on the gain control untill the clip light just goes out.This should all be done with the master volume OFF.
Than you can turn up the master volume and set your tone controls.If their is no clip light than you have to have the master volume up to mormal and set the gain control by listening for distortion, hitting the mic(s) as hard as they ever will be sung into when in use.
