Just two quick comments. Sometimes it helps to use a thin screwdriver to ease the covers off of the RF deck. ?Slight pry on the front area, then the rear, and back and forth. ?Then pry the sides slightly outward as the respective cover is removed. ?Why? ?There are at least two variants of front panels, one has a silver edge, the other does not. ?Careless removal of the covers can result in scratching the front panel, more noticeable with the one without the silver edge. Too, with the top cover off, might be a good idea to lubricate the blower bearings, and clean bandswitch contacts, etc. ? As to the bearings, I use a light, non-detergent small motor oil. ? I put some paper towels under the area of the motor, fill the oil ports to slight overflow, and then let it sit overnight. ?Minor cleanup and then it is ready for another year of service. There are a lot of experts out there that can provide valuable info about the recent topics and I'm sure they will be sharing with us. 73, Evan, K9SQG

I have not had my cover off in a long time but seem to think that there are tabs so that you have to remove the power connector before the covers can be removed.? Probably a safety device to make sure you disconnect the power supply before putting your hands inside. Ralph ku4pt

Yes there are tabs that align the edges of the two covers. But they are not relevant to order of removal. 73 -Jim NU0C On Fri, 5 Apr 2024 00:45:04 -0400 "Jerry Kessler" <N4JL.cw@...> wrote: > It's been a while since I've had my L-4B apart but isn't there a tab on at > least one corner of the cabinet (top or bottom) similar to a TR-4 cabinet > where in order to remove the top cover it helps to loosen the screws on the > bottom cover? > > Jerry, N4JL |
