Does the S meter indicate anything? You need a signal source. The internal calibrator will do but the MUTE connector needs to be shorted for it to work. The usual advice to clean the switches applies.

Flat brass stock has lower inductance than wire. ?But remember that the grids were originally grounded via an RF choke with thin wire.

To ground the grids. Wire or flat strap? I've seen both. What do you guys say?

Isn't there a shorting circuit via an RCA jack on the back panel that has to be considered?

Are all the jumpers installed? Frank Krozel KG9H Life Member, ARRL (630) 924-1600 kg9hfrank@...

I would go for the simple stuff first. Make sure that none of the tubes are loose. Grab each one and re-seat it with a circular motion to make sure that it's centered and no pins are oxidized. Past

Hello: I have a Drake R4C that went through the WB4HFN full service option about 5 years ago. It hasn't been hardly used at all. Now when I powered it up on a variac, I get power but no signals, no

I totally agree with Gary. Do not buy parts from Amazon. Mouser is my preferred vendor, with DigiKey as #2. "jerry-KF6VB via groups.io" <jerry@...> wrote: -- 73 -Jim NU0C

If you're not in a hurry, Digikey has a longstanding (unpublicized) policy that if you send a check the shipping is free. I took advantage of that, recently, to get a 115v-115v 50va isolation

*** I've had reasonably good luck at Amazon. Except for this one box of 3-terminal regulators with lots of dead ones, and ones that were grossly out of spec. But luck is what it is. Amazon doesn't

I just wanted to make a comment here. David spent a bit of time making sure he was ordering the right parts. I think “wasting money “ with the kits is a bit harsh. That extra money amounts to

Can your analyzer create a Spice model from the EP487 data? I'm playing around with Spice to see what happens to the DC operating point with different transistors. "Glenn Hetchler WB0DKT via

David, Diodes are so much better than they used to be. Now, buying from Amazon..? I think is pretty much the same as ebay..? Those parts may be good, or they may be re-labled questionable parts.?

Stick around, it will taper off after a while. Or set your subscription to web only on groups.io. "Rich W3RJ via groups.io" <w3rj@...> wrote: -- 73 -Jim NU0C

Cool. (I didn't want to miss something about other characteristics of the diodes). I think I found what I need on amazon: Chanzon 50pcs 1W 150K Ω ohm Metal Film Fixed Resistor 0.01 ±1% Tolerance

5408s are 3Amp IIRC. That is fine, you can go up rated but not down. Same with the voltage and capacitance of the the caps and wattage rating on the resistors. 73, Gary WB6OGD
