I bought my Carlsbro Sherwood combo [a Cobra 90 variant designed for guitar and microphone] in 1985 and it came with an ON/OFF footswitch for the spring reverb, a pullover cover for the amp to protect it in storage and transit and 5 pages of instructions. In the hope that they may be of some use to someone at some time, I am posting jpeg scans of the instructions.

After 12 years of once or twice a week use, every now and again, the unit
I have noticed that the topic of covers comes up with a certain amount of regularity. While I don't have any ABS lying around, there is a roll of Polytrichloroethylene which, when heated with a heat gun and pressed into a simple wooden form gave good results. I was then able to use Krylon Paint on the Inside - no wear issues. And since matte finish seems to be the preference here, I even too the PoC one and hit it with 1500 grit quickly.
Im working on a Mackie Th 12a (thump). The resistor r4 connecting jr2 (xlr jack) to J1 is fried. If youve got the schematic its on the TH-12A AMP SCHEMATIC 0021633-XX-E09-SCH page. Its just a 100 ohm resistor. Does it have a specific function and need to be replaced?? Or can I just run a wire connecting the two solder pads.

The prototype that you see in the video has a circuit with four N-channel JFET. The input stage is not like that of Jack Orman style, but is more evolved.
The high performance power supply is voltage regulated to maximize performance and minimize the hum.
Preamplifiers and all stages that receiving the first signal from the pick ups has a huge responsibility
Very nice hand guitar effects！！[ATTACH=CONFIG]17605[/ATTACH][ATTACH=CONFIG]17606[/ATTACH][ATTACH=CONFIG]17607[/ATTACH]:):thumbsup:
