    Kuzma SAFIR 9

    Love the pictures- and I’m going to ask an off topic question - appologies I see you’re on a microscope table - which stillpoints are those and what do you hear over the feet on the table itself? Do you also have stillpoints under the motor unit? Asking because I’m also a verdier user! cheers...

    Mine isn’t shun Mook, it’s simply a record weight- no locking mechanism - made by a wood turner.

    6550 or KT88 for a VTL MB450

    Thanks for sharing - I’ve used the Winged C 6550 that came with my amps when I bought them second hand, also reissue tung sol. I’ve had failures with both types, but they have plenty of miles on them. I did speak with VTL about retubing, however they wanted me to send the amps in for that...

    Natural Sound

    I see. I dont know the actual pro/con of leaving on vs on/off - will certainly be amp dependent. I don’t leave my amps running all the time - they consume about a kW, so that was one reason. I’m also a little concerned about having a failure when I’m not there to turn it off. I’ve had tube amps...

    Apologies - autocorrect sabotaged my message “ surprised you had to retube the amps”

    Natural Sound

    Hi Peter I’m a little surprised you had to return the amps - you haven’t had them that long? Did you change both the small signal tubes as well as the 6c33b? cheers Andy

    6550 or KT88 for a VTL MB450

    Thanks for the great information Marty - very helpful. I did contact Bea Lam - they are recommending the Gold Lion KT88 reissue. you’ve given me some food for thought! Many thanks Andy

    6550 or KT88 for a VTL MB450

    Thanks chaps - in terms of actual tube recommendations, I need to be practical. I need 16 tubes for these amps, so NOS would be very challenging. Likely limited to new production - VTL themselves recommend the Gold Lion KT88 reissue, My question was what changes would I expect between 6550 and...

    6550 or KT88 for a VTL MB450

    Hi All looking for a new tube set for my VTL MB450 series 1 amps. Can you give me a compare and contrast in sound quality between the 6550 and KT88 please? I know this is a pretty generic question with lots of variables, but what are the big ticket differences between the two tube types? I’m...

    AF3P pump / power supply unit

    Please make sure your glass bottles and connectors are rated for pressure use - you don’t want an accident with glass flying around. In a chemistry lab, glass ware is often used under vacuum, but only specialized glassware under pressure, and only then with safety shields.
