New in Original Box SRS360 Tube / Valve. Some boxes are opened, some are sealed.
Made in former DDR by WF (aka VEB, HF, OSW, RFT) in Berlin.It is a direct equivalent of the TB3/750 or 5867 tubes.
It is not a plugin substitute for the 3-500Z as it requires some 12V of negative bias.
PA0FRI has information and a design using this tube.
I can email a datasheet if necessary.
The tube will be shipped by registered air mail, and will be safely packed to survive.
A tracking number will be provided.
Sold as is, no returns or refunds.
Shipping cost is £ 12 in the EU and £16 worlwide. If you buy more than one ask for the shipping cost before making payment. I will try to pack in the most economic way, considering the pricing of the Post Office.
Check out my listings, there are other interesting items on sale.
I will combine shipping for multiple purchases.
I try to ship as soon as possible, but it may take 3-4 working days on occasion.
I accept payment by Paypal or wire transfer. Payment is expected within 2 days.
