Quoting schematics, etc., from HiFi Engine on other forums - is this permitted?

Having posted a request on HFE for help in fault-finding in an HK1400 amplifier, it occured to me that someone on one or other of two Vintage Radio forums of which I'm a member might be able to offer some assistance, and ideally I would like to post part of the circuit diagram in question on these forums as this might help others identify the problem. Am I allowed to post diagrams obtained from HFE on other forums, or should I just indicate that the relevant data is available to HFE Members?
