Hopefully, the RBK-16 will work fairly easily so that I can get back to the G133F. I have two Hallicrafters S-27's in my collection, and this RBK-16 is a little different from them. I also looked at the manual for the Hallicrafters S-36A, and this RBK-16 is a little different from the S-36A. This RBK-16 does not have the antenna terminals, but instead ( in their place ) it has a PL-259 connector mounted on a square of circuit board that is labeled " Panoramic Adapter ". There is a piece of wire hanging from the back of the chassis that is soldered to a lug on the rear wafer of the band switch. I am guessing that this is a makeshift antenna, and I will try to figure out if there is some useable antenna connection that comes from the Panoramic Adapter plug. The AC power cord and audio output ( 600 ohm only ) each use a mil connector. These two mil connectors are mounted on a bolt-on metal panel located where the audio output terminals would be located on a S-36A. I have a power cord with the mil connector, so the power cord is no problem. For the audio, I can use some tiny pin connectors to attach the speaker wires. With the add-on panels on this receiver, it looks like I could remove the panels and take parts from an S-27 to make this RBK just like a civilian S-36A. However, I am not planning to do this. However, here is the main difference that I see: There are two acorn tubes and a Western Electric 396A tube that is not an acorn tube. From what I have read about the other versions of the RBK's, they can have 4 acorn tubes if the receiver has the " radiation suppression tube " or else 3 acorn tubes just like S-27's, some RBK's, S-36's, and S-36A's. The WE 396A is a 9 pin short miniature tube. Is it a dual VHF triode that serves the purpose of two acorn tubes? Is this the latest design version of the RBK series or am I working on a specially modified RBK-16? If everything works OK, then I don't have any problems, but I was just curious about the WE 396A tube. Many thanks for your all's help and advice!! Have a great day and a great rest of the week!!

You will note the same progression is used for capacitors and resistors. The closer the tolerance of the part value is, the more intermediate values that are available. (Between say 20%, 10% and 5% resistors for example.) It is a "standardized" progression of values. I read how the progression was derived some years ago but can't recall how it was calculated at the moment! 73, Sandy W5TVW ----- Original Message ----- From: "Nick England" To: "Old Tube Radios" Sent: Saturday, April 04, 2009 5:20 PM Subject: Re: Why .047 capaciactor > Same reason there are 47K resistors.

Why the change from the old .01, .02, .03, .04, .05, etc. values (yes, I've run across all those in old radios)? Must be the result of the use of computers for electronic design, manufacturing and material control automation.

Too much artificial intelligence is built in to these programs? Maybe not in 'our' foreseeable future, but sometime in the future? These design programs will make changes so that the importance of the "devices" will overrule the importance of the people they are being designed for? This smacks of something that happened in a movie where a US and a Soviet supercomputer were introduced to each other and eventually started "running" the people who designed them? Sounds rather far fetched, but I think it could be a real possibility eventually as design engineers are needed less and less and the knowledge sort of "disappears" from the human and becomes dominated by the "smart machines"? Kinda scary to think about: what is a great help today in design MIGHT" turn into a lethal adversary in the future? Just a thought that ran thru my old brain! 73, Sandy W5TVW ----- Original Message ----- From: "Arden Allen" To: "Old Tube Radios" Sent: Sunday, April 05, 2009 3:39 PM Subject: How it is these days > http://en.wikipedia.org/wiki/Electronic_design_automation > > Arden Allen > KB6NAX > > Adopt a shelter dog, > save an innocent life, > and make a friend forever =:-) > -------------------------------------------------------------------------------- No virus found in this incoming message.
