This is a misleading statement, just as the statement from the manual is. R2 is bussed and must be installed in the correct orientation or damage will occur to the 8 pin comm dip.

If you look at my post closely it states R2 as the offending chip. Mr. Baldwin was at my house when the comm chip failed and witnessed this first hand.

The CTB16PC instructions says the resistor networks do not go in a specific direction.

The instructions state the following (page 14):

NOTE:

The orientation of resistor networks R1, R15, R16, R18 & R19 is NOT important.

I soldered R2 in backwards and caused the board to fail. This is a very good tip! I've noticed the instructions now have a highlight about getting the orientation right on the resistor networks. Please take your time and make sure you get the parts placed in the right direction. You'll be glad you did!

I can't find an R2 on the board.

R2 is part of the Unit ID switch circuit on the CTB16D, its orientation is important. Orientation is not important for the other resistor SIPs. The CTB16PC does not have Unit ID switches so R2 is not present.

Thanks for the clarification!

I have the PC version without the unit ID switch, as the reason my instructions said the direction does not matter.

Sorry, In my rush to defend myself I missed that you were discussing the "PC" controller. Please accept my appologies. :?:D

In the "I won't make that mistake again" department... buy the cordsets from LOR, they are a bargain! I thought shoot, I have lots of indoor extension cords I can rig my own cordsets and save a buck. These cords are about a buck a piece, so $16 right there (forget tax since tax and shipping will pretty much cancel each other out). Then the spade connectors, they are $3 for a 10 pack at Home Depot (which sells boxes of all female, Lowes and RadioShack only sell pairs), or 60ยข per cord, or another $9.60. And ya know what, most of my extension cords that will go out into the lawn are grounded, so I get to either use an adapter or twist the grounding prong off! So, for $25.60 you can have 16 non-grounded, indoor rated cords and a sore crimping hand, or for $30 you can have pre-made, grounded, outdoor rated cords. Hmmmm? I won't make that mistake again!

I could'nt agree more!! That's the best $30 I've spent.

Don't build your own to save money, but there are other reasons.

Here's a case I built.  It was actually pretty cheap (box from the $1 store, 8 sockets at about $0.39 each, and some connectors from a box of 100), but the real reason was I didn't want those big, bulky, black pigtails on this box (because of where it was located).

This disadvantage was that this took forever to build.



Another DIY example was the version where I ran 8 channels to a 9-pin Molex connector, which then plugged into a harness that went to my mega arch.  That reduced the bulk and weight.

Yes, great idea and can use futher on what I do.  I flip the light duty sinks over and this makes for a level  platform over  the capasitors and transformer. I now have a nice and level work space and removing the center lead will make the job much easier. Thanks!

With the possibility of not having CTB 16 cards in my hands by Thanksgiving, I was considering buying the kits instead and putting them together for this year. The problem is I need 6 of them. If I devote all my evenings after work to assembly, how long might this take to complete 6 boards? Or how many man hours does it take for just one board?

Never mind, found the posts that answer this...still interested in your experiences though.

VK, it seems it takes the average new builder abt 4hrs/each for the first couple boards.. the third to fourth board, you tend to knock an hour off as the placement becomes more familiar to you.. by the last set of two (boards 5 and 6) you would probably be down to abt 2hr build time each.. thats about the standard time per board now..

If you buy the kits in bulk, PLEASE remember to inventory every kit and the value of each component.. I cant state enough how important a BRIGHT light and magnifying glass are!!
