Was wondering if a rectifier tube change will brighten the Z-28 at all. I have read about them adding sparkle and what not. Does the rect.tube really change that much in tone.
What about a JJ over the EH. Or a NOS over a current production?

The changes from a NOS to a current production tube would definitely be audible in that the amp would be less dynamic. With new production the highs won't shimmer, the mids might not be as pronounced and the lows may not thump like they would with NOS.

With new production the highs won't shimmer, the mids might not be as pronounced and the lows may not thump like they would with NOS. With most tubes, yes. With a change from new 5Y3 to NOS Sylvania or Phillips to Bendix 6106 there was an improvement (or at least tonal change) each time. With the Z28 and Sovtek GZ34 to NOS RCA one- very little difference either in terms of current/voltage or tone. I'd guess because both were running at spec? Regarding whether there's more shimmer that's also debatable. With the Bendix 6106 there's more punch, possibly a little more headroom and punch, but there's actually less shimmer or at least less highs. With the 5Y3's the Phillips is a nicer (to my ear) sounding rectifier than the Sylvania and both are NOS. Sorry to upset the apple cart- it'll lead to tonal changes in some cases! Brett

I agree with Brett. It's not always as cut and dried as "the NOS amps will shimmer and the new production ones will not". I've got NOS rectifiers in all my Z's and some definitely showed a greater improvement than others. I'm not sure if it's the amp design or how close to spec the "original" new-production recto was vs. the replacement NOS. Also, not everyone can hear or "feel" the change from a new recto to a NOS. I've known some really good players who can't tell you the difference in Monster Cable and George L guitar cords. To me there's a huge difference. I'm sure guys like Eric Johnson could tell you the difference

I'm sure guys like Eric Johnson could tell you the difference I definitely think amp design has a lot to do with it. Doesn't Mike design his amps for use with new production tubes? He did with the Route 66, not sure about the others.

DC here! You can got to this link: mbsb.psy.umu.se/clips/clips.htmlScroll down to the red section - there I have recorded some soundclips - while swapping tubes around - in my Rout66. Check them out and draw your own conclusions - As always YMMV Cheers: Dixiechicken!

In my limited experience with rect tube swaps there was a considerable difference in tone and feel when I swapped from the unknown stock NOS 5y3 to an old/used Silvertone 5y3 in my RX Jr. And the change was a very positive one in this instance.

Rectifiers don't really change tone as much as they can change the feel and dynamics of the amp. NOS rectifers deliver advertised spec voltages and new production ones can be far off spec.
NOS rectifiers are also stone cold reliable which is not the case with many new production ones.
