If you want to stay with the original dual fuse plug I suggest that you always have a good ground connected first and then identify which side of the plug connects to the power switch and identify this as the "hot" or load side and put a properly rated fuse here to handle the normal DX-100 load. Then put a 20 or 30 amp (preferably slo blow) fuse in the other side (to be treated as neutral). Then make sure the outlet you plug it into has the neutral and load sides properly identified and match this to the markings on your plug. This way you greatly reduce the odds of having the neutral side fuse blowing which can create a safety hazard. Of course you can always replace the plug set with a modern 3 wire type and put a fuse inside using an inline holder but as long as you keep the rig properly grounded and use a much larger fuse in the neutral side you should be fine. Once you have worked out with the DX-100 for awhile you will be in fine physical shape to pick up a Johnson Thunderbolt which is the most awkward piece of gear I own.

Remember, I had not replaced the blown 8 amp fuses or even made an attempt to power up until I could do a visual underneath. OK with some effort flipped it over and started checking. First to notice was one of the 10K 10 Watt resistors in series with another like unit was broke in half. Didn't look burned so I assumed it was broken when I drug the unit out of the case.Looking at the schematic it appeared to be part of the clamp tube control to set the idle current on the screen of the finals and points beyond . Easy fix, replaced both with new ones. Next to notice was the HV transformer leads going to the plates of the 5R4GY rectifiers were just spliced at the transformer with the leads going to the rectifiers. Now Ive built a few Heathkits and knew that wasn't right. I took a mental note to check that out later. ( remember this one). Other then the extra wiring going to the (ugh) new external meters for grid and modulation, All looked OK. Next step was to check out the HV and LV caps, both original paper electros. Drug out my trusty Heath PS-3 and analog current meter and proceeded to reform them. As luck would have it the old power supply gave up the ghost. I said OK drug out an old Knight RC tester I had purchased a while back. Well it didn't work either. Paid 5 bucks for it and never tested. Both of these were a repair effort in it self but are now working well. Ok Thats enough for now. Good to be back. Part 3 to come tomorrow.

RF/AF pot for the BC-224 and BC-348, NOSB, $8.00 plus shipping. Fits all models. Aside from some of the knobs, about the only part where one size fits all. Also have audio packs (output transformer assembly with dynamotor choke and .05 ufd capacitor) for all models EXCEPT the BC-348-JNQ. Technically, they aren't correct for the early models but the only difference is the 250 ohm output tap. $17.50 plus shipping. Not usable in the JNQ because the choke is grounded internally. Condition unused but most need painting. Schematic to glue on top after repainting supplied if needed.

Went down to Rat Shack and bought some 8 amp fuses and doing a last visual, flipped it back over. Hooked up a watt meter, a through feed freq meter ( best 25 bucks I ever spent) and a dummy load. Well, the rig said shoot to juice to me moose, Ok here it goes expecting the worse. Flipped on the the switch and stood back. WOW filaments light up on all tubes and no arcing. I let it set for an hour and got out the manual for the tune up tests. Had some old FT-243 crystals in the 40 meter range and plugged one in. Got grid current on 40, then went to vfo and got about the same. The controls were extremely stiff, but I would fix that later. OK now for the big test, the finals. Put the Xtal switch in a unused portion and flipped the Plate switch to on with the meter to plate. Amazingly nothing happened and the plate reading was about 5 milliamps. Adjusted the clamp to zero and then did a tune up on 40 meters. Power looked good on the CW switch setting about 120 watts with grid current at 5 mils and plate at 250 mills. This thing LIVES.... Getting late, didn't try any other bands or phone. I was happy so far. Part 4 to follow. Your Friend Al BTW, If I am boring you again, please let me know.

I was asked to supply "authentic" WWII gear for a local production of "South Pacific" and told that they wanted the GEAR to be as real as possible. So I dug out the old BC-375, T-17 mike and BC-348 for them - not Pacific Navy gear but close. I chose to not provide power supplies or cables since it was only a play. When the real world descended upon the stage, it was decided that they could not leave all this "valuable" equipment there on set overnight and so it all had to be removed after each performance - just like the actors. The next decision was that it was much too heavy to move that often. Bottom line: They used the receiver as the transmitter with the mike plugged in the headset jack.The good news: there were none in the audience that knew the difference and they were all thrilled with the performance. Plus ham radio got a positive plug in the reviews for providing the "authentic" equipment.
