Photos 19, 20
Vacuum tubes removed from a total of 4 Matsushita Communication Industrial Power Amplifier WP-601 units.
*This listing is for a total of 20 vacuum tubes only.
This is not an amplifier.
6CA7: 8 tubes total
5AR4: 4 tubes total
Model Unknown: 4 tubes total (characters were unreadable on all 4)
6BL8 (smallest ones): 4 tubes total
Total: 20 vacuum tubes.
The WP-601 units themselves are quite old.
I personally removed the vacuum tubes from them.
Operation has not been tested in any way.
Please consider these as junk items.
Visually, one of the long, thin vacuum tubes at the bottom has a transparent top.
Black soot was falling from the 6CA7 tubes during photography, so I was wiping them as I took pictures.
I have no knowledge of vacuum tubes.
There are no cracks.
Please bid if you understand what you are looking at in the photos.
Will be packed securely and shipped in a 60 or 80 size box.
Thank you.
