Nice to read something about your Wallace Amp in that article, Bri...
Congratulations! It would figure that the amp sent for review would be slightly damaged
in transit! At least they DID mention that fact, and especially that the amp still performed perfectly
for the review and came out "like a Champ" (pardon the pun)...
Anyway...LONG overdue!

okay, I have to play devil's advocate here. :twisted:

I can accept the subjective conclusions but as for the amps--these do not appear to be quite so 'apples to apples' in comparative terms namely because if you look at the chassis pics closely, some of the circuit values appear to be different, so I'm not really sure you could call that a "JTM45 roundup".

-the original JTM45 appears modded/molested. There may be an extra cathode bypass cap at V2a(hard to make out for certain)

-what I can see from the reissue leads me to believe that the intension was to basically mod the amp towards the later 1987(split cathodes, EL34s installed) circuit. If it sounds good that way great, but... :roll:

-Wallace was described as "darker". MetroAmp, Metropoulos both have a pot cap. Wallace doesn't appear to. Would have liked to hear impressions with a pot cap on (say a cap with alligator clip ends).

-also, would have liked to known the specific tubes(article basically says new production) for the Wallace

Kudos on finally getting some prime time action on your fine sounding amps! It's about time and it looks like you definitely got the extra love in the form of the "damage" article which helped you come up smellin' like a rose! I'm sure you'll be getting alot of renewed interest in your work from here on out so go get'um!

Dai,

I don't use a bright cap on the volume because I think it makes the amp too bright. This goes for my 66 as well, it's just too bright with it on the pot. When the amp is cranked the cap doesn't even matter really.

thanks Brian :) IIRC that guy with the vintage Les Paul in Germany and the super YouTube clips--Ingo Dirkschneider...(errrp, no that's something to do with the Accept guy :lol: ). UDO(!), yes that's it. :oops: Udo the Pipper. Anyway his apparently had none so I've no doubt sans bright cap(s) can sound good(or great). 8)

I thought the article was pretty fair. I like that they mentioned differences without making the subject judgment of "best". I know some people want that but I don't think it exists. I would have liked the article to be more technical. Like pointing out the absence of the bright cap and therefore making sure to test the amps at full volume where the bright cap doesn't matter. But some people will want the darker amp so being somewhat unique is a benefit.

It was pointed out to me that the original JTM45 in this test might actually have a 139 OT which makes it pretty far from original if that is the case it really throws this comparison in the garbage. The wire colors don't jive with what one would expect from a 103 transformer. There is just too much importance in the mind of the reader that being close to the original is the goal and if the goal is in the wrong place you loose, if you get my drift. That is very unfortunate as these articles are always regarded as some kind of holy grail in authority. Also if true shows how totally ignorant of any technical aspect the testers were.
