No you're right, in this case TF's amp is a Relic'd Fender Deluxe type amp, using 6L6's for a bit more power, plus some other tweaks.
Ian's is a standard 5E3 Deluxe, with Power Scaling. Horsehead has a 5F6 Bassman head, and all 3 of these are Tweed covered. Just to throw a googly in, there's currently a JTM45 replica and 2x12 I did for sale in Johnny Roadhouse, also in Tweed!
The EL84 amps I do are variations on the Watkins Dominator/ Marshall1974 design, which doesn't sound Vox-like. There are some I've done which are tweaked in a Voxy manner! :)
