87 vs 93 SLO100 gut shots

[johnnyjellybean]

Comparison of an 87 to a 93...... note the different amount of components, the different circuit board paths and the different physical placement of parts.......
and yes!! they sound noticably different.

the 93.......

the 87...........

which do you prefer?

 

[johnnyjellybean]

I prefer the 87. A little smoother, rounder and a little more of that Soldano mid honk. Also a little more gain.

I've been saying it forever they are different - even though Mike says there not. Everybody tells me I'm full of it. Posted the same kind of gut shots. I have #19 ('88) and a 2009. And yes they sound different. Depending on what you like would determine which you prefer. I keep NOS in the '88 and use it more in a Rock kind of way, where as the '09 is stuffed with Chinese and 5881s and is used in a more Modern type way. Both are great.

Well there is no denying that those 2 circuit boards are different along with some of the components.

The old amps had carbon and carbon film resistors. That in its self will change the tone.

He should have marketed it better like Bogner does. Make a 10th Anniversary SLO and upcharge. Make more $$$.

Now there's a goldmine right there. Do the chrome transformers and name plate.

I have a 25th rackmount on order for exactly this. Chrome face plate to match my VHT Classic

Nice!

Me thinks the add. loop in the later SLO makes a bigger difference tonewise.

#008 had a loop and although there was definitely some tone sucked out by the loop , it still had the inherent difference that these 1st amps have compared to the later ones.

And it had just 4 preamp tubes?
I'm confused now . . . the pic above ('87) just shows 4 preamp tubes which would indicate either no loop or some sort of passive loop. The "newer" one has the (standard) 5 12AX7 with two triodes for the loop . . .

The one shown is #006 which I currently own. #008 which I previously owned for quite a few years, had 5 preamp tubes. Other than the loop,they were identical. These were the amps that were shown at NAMM 87.

I see, thanks for the clarification.
The loop makes a big difference, not that I ever had the pleasure to play such an old original SLO, but I've built several "clones", some with and some without loops and liked the non-loop versions better, because they were less compressed sounding than the looped versions.
