HA 460 fan

[W5CEM]

Going to get my feet wet with an HA460 on 6 mtr. AM!  Couldn't bring myself to use the K3 on AM!!!

I notice in several pictures the addition of a fan to the rear of the enclosure...placed near the transformer.  Is this advisable?  I figure if one fellow did it, it can't hurt, but looking for the opinions of the esteemed before I track down a 12v point and do the install!

Having spent my youth as an AM DJ, I suspect this will be my launch pad into more AM operation!  I did miss the glow of the tubes, so the new rig helps satiate my lust!!

Actually, its the underside of the chassis that gets brutally hot because of almost no air flow. The top side has vents to dispel the heat from the tubes. I only saw one on the web with a fan mounted on the back directly behind the transformer. Given the position of the fan and transformer, I can only assume he's trying to pull the heat from the transformer. Probably can't hurt, but tons of HA-460's and HA-410's have been running for the last 45 to 50 years without a fan and they and their transformers have survived.

You guys were wondering? This beautiful radio is what she wants for Valentine's Day.

I agree with Pete.  Top of chassis is ok [well, reasonable anyway] for air flow.  It's the bottpm that gets hot.  I've run mine since 1969 without a fan and without problems.
