The attachment shows the partially assembled chassis. Note the adaptor plates to fit B8A valveholders in lieu of the octal sockets.
Both IF transformers have that common fault of detached iron dust tuning cores. It's usually the lower core that seems to go first. Superglue is ideal to effect a repair.
