Some notes on the EOTS PCB. 

 

 

An array of clipping diode options 

are available! 

In the TS808MAX you will use them 

all. 

Jumper JP1 JP3 

and JP5. 

 

Keep adding 

solder until 

they join. 

You will use T1 

in this kit. 

T2 remains 

empty 

You also use fat 

The bright toggle is optional for all 

versions.  

If you did want to add it in then you 

use a SPDT on on and wire it in. 

You also add a 100N at C9. 

You use the clip toggle. 

Voice pot is not used 

If you aren’t using it you need 

to jumper the left pad to the 
middle pad
