Just placed the order for the resistors. Used Itzbitz's excel file, but made a few changes taking into account a few out of stock resistors at mouser, and also trying to move some pairs even closer to 50K ohms. This is the list of resistor values I got:

[Edit]Ordering of rows and columns corrected:

(1) 49900 - 0
(2) 49900 - 51.1
(3) 49900 - 121
(4) 49900 - 274
(5) 49900 - 392
(6) 49900 - 562
(7) 49900 - 750
(8) 49900 - 1050
(9) 47500 - 1400
(10) 47500 - 1690
(11) 47500 - 2150
(12) 47500 - 2490
(13) 46400 - 3160
(14) 46400 - 3920
(15) 46400 - 4990
(16) 43200 - 6340
(17) 42200 - 7870
(18) 39200 - 10500
(19) 38300 - 12100
(20) 34800 - 15000
(21) 30000 - 20000
(22) 24900 - 25500
(23) 15000 - 34800
(24) 0 - 49900

In parenthesis: position in the attenuator
Left column: Input-to-Output resistor values (inner ring in the Elma)
Right column: Output-to-Ground resistors (outer ring in the Elma)

I know that it has been a while but Elma has yet to ship the attenuators to me. I plan on calling up tomorrow and finding out what is going on. Again, I am sorry for the delay.

For some reason I thought you had already shipped them to us... well at least I can stop worrying now

Any more news on the second batch?

They should arrive on Elma's dock on the 18th of October. They will ship them to me then. Sorry for the delay.

 

[philodox]

Any updates?

Also... I was wondering. I know this is rather large... what would you figure is the smallest hight enclosure that would fit one of these elmas?

Looking at mine (from the first batch) it is 8cm (3.2") long (from mounting ring to rear of the switch) and 4.5cm (1.75") in diameter (for the PCB parts, the widest part of the switch). I wouldn't try anything less than 5cm (or 2") inside height, and that'd be really, really tight.

Talked to Elma last week. Attenuators were supposed to arrive sometime this week. I just checked my paypal account and no money has been withdrawn. I hope they just withdraw the money when the attenuators arrive to them. This is the second time I have placed the order(first time it never went through.) Anyway I will call them again and find out what is going on. I am sorry for the delay.

No problem, I wont have my passive preamp design finished for quite a while anyways... since I know nothing and have MUCH reading ahead of me.

Talked again to Elma today. They said they would deduct the money from my account when the attenuators were shipped.

 

[philodox]

Any word on these yet?

 

[CBMC]

A talked to Elma about 2 weeks ago they told me that they were on their way(from Aus., I think). No money has been taken out of my paypal account. I will call them today and find out what is going on. I have placed the order twice now, hopefully the third times a charm. I have 2 attenuators of my own that are not being used at the present, I plan on sending them out to 2 of the 4 attenuator buyers. I will just take the top 2 off the list. I will then just keep 2 from the next shipment. Again, I am sorry for the problems that have occured. Elma was so easy and fast the first time so I really don't understand what is going on.

 

[CBMC]

I finally received the attenuators from elma. I will ship them out tomorrow. I have one extra if anyone else is interested. I will ship to everyones paypal address unless you tell me otherwise.

 

[philodox]

Sweet, cant wait to see this thing in the flesh.

 

[dcrane]

I finally got it today. I was so surprised that I almost passed out.
