wavetek sweep

I remember that I bought while ago from a flea market a baby like this, for a few bucks, but after relocation I didn’t take with me.
Originally had the same problem on low output power level. The bad component was the output attenuator that probably does not support too much reverse RF power or DC.

Yes, The attenuator is defective. Few resistors r burnt. Where to buy a new attenuator? or simply how to match resistors values & repair it?
