VTL TL-7.5 series iii

[markramler]

Looking for some info , I found a 7.5 iii I was intrested in purchasing. After scrolling through some posts on web and here it sounds like it could be needing updates to bring to current specs ? Am I understanding this right

You are correct. I purchased my 7.5 iii in 2012 and updated it in 2021. You need to email Bea Lam at VTL with the serial # of the unit and she can advise on what upgrades are available.

VTL believes in very long product cycles. So sometimes there are minor in-production changes, but the model number does not change.

I would not characterize an older sample as "needing" updates. You might call Bea and give her the serial number of the unit, and ask her if there have been any in-production changes, and, if so, how those changes might affect the sound of your current component.

The upgrades were as follows:

They replaced the gain stage boards where the tubes are mounted with a new and improved version – The new boards use better components that reduced the constant tweeter noise.

They updated the control unit power supply with a new adjustment system for the FET devices, as well as other updates to bring the old power supply as close to the current version as possible.

A complete replacement of the four volume attenuator boards with new production boards that includes new, much more precisely matched relays. These new relays are very quiet and eliminated any of the slight pops that I heard when the VTL is first turned on and the volume steps are adjusted.

Overall, there was an immediate noticeable improvement in sound quality. There is a lower noise floor, a sense of effortless music flow and presence filling a larger soundstage. Clarity and resolution have improved and yet it still sounds tonally correct but more accurate. The Telefunken NOS mid-60s also help to optimize performance.

Hi Mark, thanks for sharing the knowledge you have regarding the upgrades. Do you happen to know the rough date/year each of these updates were made to the model? It's really confusing when a brand changes the design of a product without any change in name or published communication. Thanks.

I do know which update corresponded to which year. I purchased my VTL 7.5iii in 2012 when it was first released so I needed all the upgrades. If you have an existing model you can email Bea with the serial # and she can advise you what upgrades are available for that model.
