Dmans if you have any recommendations regarding the VNA I'd love to hear them. I have one arriving later this week.

I want to thank everyone for their help! Without it I'd have a very nice looking paper weight...or boat anchor lol! Yes the Range Gain II alignment instructions are definitely the way to go. As soon as I get a minute I'll get to it. Thank you for the info guitar_199!

Let me start by apologizing as I can see how confusing my post has been now lol! I've actually been working from the Sam's so my tube references have all been related to the Sam's tube labels. I've continued working from the Sam's because it has voltage and resistance values that the owner's...

Thank you for the reply. No the diagram I posted is from the Regency Range Gain owner's manual and it is how mine is wired particularly related to V7 which is completely different than the Sam's. I think there are considerable errors in the Sam's when it comes to V7's wiring. For the most part...

Perhaps someone can edumacate me. Where does a negative grid voltage originate from or how is it created/injected? The reason for the question is that that's where the problem lies in this radio. The grid (Pin 2 of V12) isn't going negative so it isn't stopping the flow of electrons. "Because...

I figured I'd post the owner's manual diagram here for historical purposes in case someone else encounters this.

15vdc on both sides. At this point I'm convinced that the problem is at V12. What I don't understand is why I have the correct negative voltage on one side of the RF choke but the incorrect positive voltage at the pin. I tried removing the neutralizing gimmick (unfortunately I destroyed it in...

****EDIT**** I compared the wiring diagram in the Owner's Manual to the Sam's and the Sam's is indeed wrong. I figured I'd leave this post in case someone else encounters this issue in the future. I just realized that I forgot to hit post yesterday regarding V7 (6CM8). It is not wired as stated...

I figured there might be some skepticism about the voltage inversion so here are pictures showing the values when keyed. As you can see there is a negative voltage inversion through the 6.8k resistor and then a positive inversion through the RF choke. The Sam's shows that there should be a...

I also forgot to add that I wonder if the V2 pin 1 value of 260vdc isn't a typo duplicated from V2 pin 6. If you look at the other 6AN8 (V8) Pin 1 is 180vdc....just about what I'm getting at V2 pin 1 (184vdc). V8 Pin 1 is fed 270vdc through a 33k resistor to get 180vdc. In my case getting...

So the voltage issue on V12 Pin 2 appears to be related to the RF choke L16. I have -16vdc going into it but 9vdc on the other side. Is it safe to assume that it's toast and is there a replacement someone can recommend? Thanks! EDIT: I had to add this because I've never observed this before but...

Sorry that's a typo. Too much copying and pasting between here and emails. 184vdc is correct at pin 1. 159 is an erroneous number. I also swapped tubes from V2 and V8 with no change just to throw that in the mix. I'll have to lift one leg of R66 later tonight.

So V2 is the 1st and 2nd rec-transmit oscillator and Pin 1 should be 260vdc per Sam's. It appears to be fed by 270vdc (260vdc in my case) to a 22k resistor. The resistor then feeds A10/L12 (ferrite or slug). I have 260vdc on the primary side of that 22k resistor but only 159vdc on the other side...

V2 is the receive-transmit oscillator and V12 is indeed the final output tube. Disregard the values for V7 as it's wired differently than the Sam's. I double checked it today and I'm going to edit the post with correct numbers. I appreciate the reply and that gives me a direction to look in. Thanks!

I took voltage readings on all of the tube pins. Tubes were in. The first number is the number in the Sam's. The second number is my reading. V1 Pin 1 : 45 = 47 Pin 2 : 0 = 0 Pin 3 : 1 = 1 Pin 6 : 80 = squelch open 102/closed 109 Pin 7 : .1 = squelch open -.6/closed -1.2 Pin 8 : 4 = 4 V2 Pin 1...

Sunbulls how are you doing? We haven't chatted since that Smokey CB you, guitar_199 and I were troubleshooting! Currently it has an amplified D104 wired to it (the gold one pictured). When I first started troubleshooting it, before committing to this particular D104, I used the cable with the...

Guitar_199 here are the values you were after. 300vdc source = 312vdc 270vdc source = 258vdc 180vdc source = 210vdc 150vdc source = 178vdc On channels 1 and 23 it keys about 3/4 of a watt (modulation is turned down on the mic but up on the radio) and swings to about 3.5 watts with a whistle...

Thank you Dmans and Guitar_199. The reason I could not perform step 1 is because I do not have access to a sweep generator or a scope. If there is a work around to that then I will gladly perform step 1. Guitar_199 I will get those measurements and post them here. Thank you both for your replies!

So I went ahead and performed all of the steps for alignment that I could with no change. The voltages at the 6AQ5 tube pins ( V9 and V10) are spot on. There are some issues with the 12BH7 final tube values though. Here are the numbers for it. The first number is the value in the Sam's. The...

I have a Regency Range Gain that is in excellent condition and freshly recapped. The resistance at the tube pins is spot on and the only resistors with issues were the two at the caps and the 27ohm resistor that runs from the bridge rectifier to the cap; which was blown. All were replaced and...
