If your DSL401 is using that board revision and issue number, the choke would replace R32.
As for using a transformer, seems like overkill. A 3H choke is so cheap (and lighter), I'd just use a proper choke. I've got DSL trannies on my website but you can use almost any 3H choke.

In terms of tightness, try a 1uf cap on V1's cathode (C83). There's no point in having so much bass come through so early in the gain stages.
For harshness, perhaps the speakers are a problem? Not broken in yet? What kind of speakers do those little combos come with? What do you mean by harsh?
Yes, it has a revisionised PCB, it's a 2007 model. I dont see R32 on the schematics, probably because it's pre 2003.
I'm in Croatia and I dont wanna mess with paying, improting, waiting min 10 days... etc. when something laying around in my home can do the same job. It's also a bit of a challenge, experimentation. A little bit of weight wont kill me (or my friend, the amps owner)
The amps speaker is a celestion 100w goldback, not a very good one but I think a reasonable tone can be get with it in there.

The harshness is manifested as a sort of fizz in the upper frequencies, doesnt go out even with the treble down. Maybe changing the cap around the plate resistor to a higher value should help this.
