spigot bearing in centre of flywheel? tho - it should be noisy at all times if stuffed
if it's only two gears, then could be:
synchros for those gears
needle-roller bearings for layshaft in gearbox flogged out at 1-2 end
does this happen as the clutch is slipping (while clutch pedal is moving from disengaged to engaged) or after is in gear and under power?
clutch would only be culprit if it's while it's slipping -if its fully engaged, alook elsewhere.
also, have you done a slippage test on the clutch, find a steep hill and drive up it 1st second and low revs then floor it, if slipping engine will overspeed compared to actual accelaration.
have you gone lo-tech with this? get under car and look for new scars/scratching on/near exhaust pipe - particularly near the gearbox - i once thought my engine had developed vibration problem (e.g. clutch/flywheel rooted or loose) turned out to be exhaust vibrating on end of bellhousing - was not obvious from looking thru engine bay, but from undeneath was visible

clutch isnt slipping at all, tested that. no new scratches, nothing rattling against anything else. This gearbox doesnt have a spigot bearing! argh thanks tho, is there anything in the gearbox that could do it, ie it only does it on take off ie more load on box/clutch?

i'd say it's a bearing somewhere - as it's only those two gears, i'd point the finger at the synchros for those gears. do you get any noises if gently cruising in 1st or second?
what about other parts of the drivetrain? diff? drive shafts?

no the noise is made in any gear you take off from a stand still in... ive tried reverse 1st and second, if the clutch is engaged it doesnt make any noises....
when you drive and back off the gearbox makes a slightly audiable noise ? what could it be in the gearbox?

just a thought - you car is mid mounted engine - so are the engine/gearbox mounts alright?
if they're stuffed, the engine could be moving around too much under load (or backing off after applying load) and something it hitting something else (drivshaft on fixed thing, or engine hitting chassis or...)

no its not the mounts, maybe something in the gearbox? spinning type noise, but the bad thing is the initial clutch gripping noise.
