Before

After
The Hallicrafters SX-115 receiver is one of those radios that has a couple of relatively difficult to change light bulbs, i.e. the Tuning and Band Selector lamps. Thus it is a good candidate for white LED lamp replacement.
Lamps Used:

Four LPW-WIDEA6 for the frequency display area, Tuning and Band Selector illumination.
One LPW-DIFFU6 for the S-Meter.


Before

After
The Central Electronics 100V transmitter. The PTO lamps are hard to get at and you have to be careful to avoid damaging the dial cord.  The semi-transparent material used in the meter and  PTO display areas is a yellow colored  so it remains so even with the LED lamps.  I'm not sure if this plastic was yellow at manufacture, but I have never seen a CE-100V that wasn't this way.
Lamps Used:

Four LPW-WIDEA6 for PTO and linear logging scale.
One LPW-FROST6 for Meter.


Before

After
The Henry Tempo One transceiver.
