Need a little help here.
Got this 6SL7wgt SYLVANIA tube - but right out of the box I noticed the cloudy, white top.
The tube works - slightly noisy, but I only dared to run it for 10 minutes.
What is your opinion - is this a sign of leak?
Would you dare to use it?
So, I just came across an article discussing how the current “situation” in Ukraine is going to affect the tube market, that is, how it’s going to affect Electro Harmonix (EHX) and its brands: Tung-Sol , Electro-Harmonix , EH Gold , Genalex Gold Lion , Mullard , Svetlana, Sovtek
What do you guys think?
Note: I do not want to spread any fake panic, I’m genuinely just trying to spread this news and hear what everybody thinks about the situation and the future of tubes
It’ll probably push tube prices up, at least new manufactured stuff. The Chinese manufacturers are still manufacturing AFAIK.
It might have a bigger effect on the availability of the NOS Russian tubes that have become popular on input stages like the 6C45Pi or 6N1P. Though the effect there is more likely disruption in shipping.
It is what it is.
If the prices are going up, I think it will be by a great amount.
The big concern is the fact that exporting tubes of the seven Electro Harmonix brands is banned until the end of the year. That means that we will not see any Electro Harmonix exported from Russia until the end of 2022. Pretty big stuff if you ask me…
People could buy weapons and bullets made in the former Soviet Union they can source russian glass tubes. Likely there will be a middleman involved somewhere in SE Asia. Will likely take time for them to pop up. Hell ebay still might sell them.
Thanks for the link. That response had some entertaining posts in the comment section regarding amount of time when tubes begin the process to audibly deteriorate. Fresh sound from fresh tubes? Someone stating that just unplugging and plugging back in everything gave them a fresh sound. I wonder if that listener is experiencing issues with oxidation of metal somewhere and the physical movement of unplugging metal points of contact is removing oxidation.
