While they're not exactly "budget" priced, the Magnequest RH-60 SE OPTs sound excellent with the GSG. These have 5K primaries, and 8/16 ohm secondaries. THese are about the same size as the Hammond 125ESE or the 15 Watt GXSEs. The output power will be somewhat lower than with a 2.5 or 3K OPT, but the THD is also lower, which is a good trade-off. These are about $100, each. Higher quality iron at a price that won't break the bank...
I've used the GXSE OPTs in other SE amp projects and they sound very good, and give the best "bang for the buck" of any OPTs I've ever used.
I have a pair of the 3K, 10W Transcendars, I'll have to try them out on a GSG, and the other test I want to try is to run triode strapped 6AV5GAs.
Ditto, with a pair of Edcor GXSE15-8-3.5K. Or use Soren's method, with using the GXSE15s with 8K primaries, and 16 ohm secondaries, and run them as 4K:8 ohm OPTs, that might offer a higher primary inductance, at no extra cost.
