These were also given to me a long time ago.
When I acquired them, they were checked and deemed to be in good working order.
They have been stored for several years since then.
For this listing, I have only performed a visual inspection.
I assume that those viewing this listing are knowledgeable individuals, so please assess the condition, type, etc., from the photos and make your own judgment.
I have not performed any checks with instruments.
I have only looked at them and taken photos, and from what I can see, the exterior appears to have no particular issues.
I have not tested them on actual equipment.
Only those who understand what unchecked means should proceed.
I apologize, but due to severe presbyopia, I may misidentify the vacuum tube model numbers or their condition.
I trust that those with extensive knowledge and excellent judgment will be able to discern all the details from the photos.
Please make your own determination.
