Re: Conversin from ECC808
Hi Vlad.  
 
 
 
Unfortunately all these tubes have different pinouts! ECC83 also uses three pins for the heaters, the others two.  
 
The ECC88 takes lower plate voltage than ECC808, and it has much lower gain. It's more suited as a driver tube than a preamp tube.  
 
 
 
If it's possible to solve the connections on the PCB, I guess it would be best to convert it to ECC83.  
 
 
 
You can find data sheets for all these tubes at Duncans: http://duncanamps.com/tubedata/  
 
 
 
I guess you have some problems finding ECC808's?  
 
 
 
Good luck!  
 
"Edgar"
