Asembled and ready to use with all original parts that come with glassware kit.
Good up to 400V of DC out voltage.The heater are now for 6,3V output voltage but you can change that to what voltage you want.The both heater regs can be made also als symetrical supply if you need this.The board comes with original manual.Price 100 euro plus shipping.This board works perfectly!!

Becose of some questions.
The main psu caps are now 400V 330uf Nichicon and with this you can use this board now for up to 350V B+ voltage!The bouth LV regs are using LT1085 ,so for up to 3A,but the limiting factor are the heatsinks,this are for up to 2,5watt/each of thermal dissipation!This board is verry good to use for some tube line stage or preamps or phono amps.The HV section you can use for up to 50mA of current with center taped transformer up to 100mA of current.The HV section diodes are now Sic Cree C3D02060 so for up to 600V.If your current demand is low let say 10-20mA you can go with B+ up to 450 volt also but in this case you must put a new HV caps with higher voltage ratting on this board!Also verry good is that you can use LV heater supply with standard transformer or center taped or if you wish you can get for tubes that can run on 12,6V dc heater supply with voltage doubler from 6,4V transformer secondary!For more info and use plese look on Glasware audio store site.
