Hi up for consideration is a single 83V NOS Tubes , made in Australia

Packed in its original box , basically a 4 pin version of a 5v4

could be used to uprate an 80 but would advise caution as it would increase the voltage by as much as 60volts

you are buying one tube only ....

thanks for looking.

If there is a particular tube you are trying to obtain then send me a message and i will see if i have it .....there are so many tubes to cover that listing can be quite a job to keep up with.....

Please note that I can send parcels through budget postage that can save you some cash however ebay will not cover you if the parcel is lost .....Australian economy post does register the item and issues a registration number but does not issue tracking with it .....please send me a message regarding this prior to checkout if you wish to do this.

If you choose economy post then YOU become responsible if the parcel is lost and no refunds will be sent for non collection..
