SP is for connect the circuit to which way you prefer.
I think SP1/4 is for the output mode of the power tube, you can either jumper them ( I'll be using a switch so I can test the different mode).
SP2/5 is for different heater voltage which I will just jumper it to keep at 6.3V
SP3/6 I have no idea and since I don't have -V, I will just jumper it to Gnd.
Post cost from USA to AUS is unaffordable so I'm forced to get from China/ebay.

I actually built a amp using this board, but I modified the part values to make it work with rarely used 6y6ga and 6y6g tubes. These tubes only use about 200volts and only put out around 1.5 watts in SE. That 1.5 watts sound very sweet with the pairs of varied fullrange speakers I have, but that's probably not what your looking for. Therefore I cant tell you how it would work with a KT88, but I can tell you the boards are of decent quality and the seller is trustworthy. I have also bought some other items from him and have had no problems.

I was looking to this chinese boards for tube amplifiers.
As i posted before im new to amplifiers and want to make something simple for starting.Thinking for KT88 for final to get more watts.
Will be this good according to the schematic?or i will throw to the bucket my money.Please remember that i want something good to sound but without toooooo much money,tubes,weight etc.
something to build for the start.
i prefer to give money for good OT.
Thanks
George
