After some great replies from last week, I've decided to part with my Delta II -- simply too many Ten Tecs. This was a small restoration project from an estate --needed some general clean-up, a new E
Curt, Please send me a copy as well. - I have a Triton IV I am refurbing, and one thing I am going to try is creating a 245 filter out of 2 NE-QRP NESCAFS (two SCAFS, one for each setting). Then each
Can this be done on either of these rigs? (at least +/- 5 KHz, 7 would be better) If so, how? Thanks. Would really like the opportunity to work "split", at least for the guys working "up 5, up 5". i.
I have a Delta II that I am refurbing, and it appears that the internal speaker has some sort of issue or short. After a few minutes the audio gets very distorted, and the audio amp module gets very
re: external jack I will take a look.... thank you for the suggestion. It would make sense considering the internal speaker still works. I agree that an external speaker does sound better, but if I e
And your cat may be leaving for other territories because when that series RC isn't there the amplifier will oscillate at ultrasonic frequencies. Its a parasitic suppressor. Thanks guys... I'll take
Bill, Good point about reminding us that the external speaker works, and no excessive heating. The series RC on IC audio stages is NOT switched out, especially when using an external speaker with ext
Issue closed. Not sure who it was, who mentioned they had been in their Argonaut II recently, but upon closer inspection the entire top deck of these rigs is hinged, and swings up. (I am so disappoin
1. Did all Delta II's need the AGC mod (I.e. did Ten Tec ever change the values to shorten the time constant, or are all Delta II AGC circuits the same)? 2. I have one that I am re-furbing that has t
Is there a "beefier" replacement for the single pass transistor on the back of the 252 supply? 2N5301; NPN, 40V 30A 200W I have to replace it every few years (good thing for crowbars), and was wonder
Jerry, Could I just swap in a darlington pair like the 2N5686 (80V, 50A) and loaf along at my 18A, and be that much further inside the max current limit (and less likely to fail?) http://www.onsemi.c
Jerry, So what causes the pass transistor to fail? (my crowbar is after the pass, in the cable... added after the first fail took out half the IC's on my Omni back in 1980 (under warranty, thankfully
Thanks to all that commented. Plan of action will be: Replace the current pass transistor with an NTE181 (not cheap, about $6 at Jameco), but has the best combination of power handling and break down
PLEASE CONTACT LEE AT THE CONTACT INFO GIVEN. DO NOT REPLY TO ME. I am a personal friend of Lee, and can vouch for both the seller and the condition of this rig. Bill W1PA -- For Sale: Ten-Tec Omni 6
Got a call from Lee this afternoon, and he has decided to keep the Omni 6+, so it is no longer up for sale. Thank you to all who called and inquired. Bill condition
