Oscillation on the EL34 grids. Can this be CCS related?

I am running a williamson type of circuit that I have tried to improve by using K and K CCS kits. The setup is a 6h30 as a preamp/splitter, ecc99 as a driver and EL34 triode wired. I have installed the CCS as a plate load everywhere but the phase splitter. Everywhere voltages and currents are on target, but the quiescent current of the output tubes is by no means quiescent. It just oscillate and I needs to shut the amp down before the tube gets overpowered. I was wondering whether it could be CCS related. Any help will be appreciated. Sincerely,
Francois
