Description

 

Very rare tube in perfect condition, looks NOS, tests even better.  Shipping is 10$ world-wide no matter how many tubes are ordered. I will be happy to combine shipping.


Item:

For sale is one (1) Triotron A430N, equivalent to REN904 and MH4. 

Most likely made in Austria in the 1930ies, this tube looks great and tests fantastic. The A430N is direct substitute for the REN904. The metalization has only minor blemishes from the last 80+ years. 

The tube tests with nearly 120% of a new tube and I guess it was never used since production. 

This is a very rare tube and a perfect fit for any serious pre-war tube collection…. or simply as a nice tube in any set-up that requires a REN904. 

Please
see my other auctions for hard to find tubes. More to
come…. please ask if you are looking for a particular type, I may have it!

 

I also do have more REN904 and other pre WWII tubes. Please let me know what you are looking for and I will be happy to check my stock for you. 

Please check my feedback and buy with confidence!

Combined shipping available on multiple purchases: 10$ no matter how many tubes you are ordering to any corner of this planet!

I

Shippping


I usually ship within 3 days after payment but always try to be faster….(it always depends on my business travelling).

I will ship to absolutely any corner of this planet for a flat 10$. No matter how many tubes you will be ordering and I will be happy to combine shipping. Please be aware, that remote destinations (seen from Western Europe) may take some extended time for delivery. Also slow customs and postal service at the final destination may slow down delivery extensively. However, most parcels should arrive with 10 to 15 days after marked as “sent”.

Shipping will be as registered airmail parcel from Deutsche Post including a basic insurance (50$ per parcel). I will provide tracking codes after shipping, which allows tracking with most local postal providers like USPS etc. as long as your home country participates in the international postal tracking system. If your home country does not participate in the international postal tracking system, tracking will end most likely at the German border.

If your country participates in the international postal tracking, you will be able to track this parcel with the tools provided online by your local postal service (e.g. USPS Track & Confirm or Hongkong Post Mail Tracking)

If you want/need full insurance on your parcel, I can also provide this for a modest upgrade price to most countries. Please ask me after ordering if you want to have a higher insurance on your parcel.

Orders of 200$ and above will come with a higher insurance automatically without any extra charges.

Please be aware that there might be additional import taxes in your home country if you live outside of the EU.
