Hi Danny,
Consider having Craig from NOSValves to modify your Jolida Amp. I have a Jolida 502B converted to triode with EL-34's. Other modifications included Hexafred fast recovery diodes, Jensen PIO caps, tantulum resistors, bypassing the balance controls, DACT 100K attentuator, some Cardas re-wiring. nice Mullard pre-amp tubes and some Swet EL-34 power tubes.
The Jolida with the Cornwalls sound very nice. I've also acquired a re-furbished EICO HF-81 from Craig, and this sounds sweet also.
