If anyone is interested, "ice blue" LEDs are now available that are a good match for the correct Drake aqua blue gels. I recently used one in my TR5 to replace a #53 lamp. LEDs surround the top bayonet like a turret and in the TR5 it results in even lighting across the meter scale.

I have some cool whites somewhere. This one is pretty bad. Attached pic is with warm whites behind. Before anyone says anything, the meter is off-scale left due to a static charge. After I let it dissipate the meter works fine. 73 -Jim NU0C On Sun, 10 Mar 2024 10:29:17 -0700 "Steve Wedge, W1ES/4 via groups.io" <w1es@...> wrote: I have an outlier L7: one meter is normal and the other is "yellowy" I have reduced the apparent difference by using a "warm white" LED behind the normal one and a "white" LED bulb behind the yellow one. -- 73 -Jim NU0C |
