Grabbed 4 curious to see if the help with my microphonic tubes and if there is a SQ difference.

They might as they are made with the same vibration reduction base and when I tried these with the Heerlen E180CC/7062 1957 PW in the LP they were quiet with no noise on the LP!

Think the heater current is too high for the LP.

I found a post that had the E180CC / 7062 listed as 400 mA so that is at the limit of the PS.
Dr. Cavelli suggested no more than 350 mA in the LP be safe.

I had microphonics issue with this tube when plugging directly into my CTH. But after using the socket saver, the problem goes away

You are correct TK (thank you) the heater current is too high for the LP. I was checking tubes I had with different gain ratings to see where the LP became noisy.

Mullard ECC82 57' Blackburn Square Getter Long Plate = Best Bass and Mids, I have ever heard! I am swimming in waves of midrange and bass texture.

Brimar ECC82 56' Square Getter Long Plate, up next.

As usual, TK16 was spot on, with tube suggestions.

Hey @TK16 ….found something for you. Here's your chance to scrap out that piece of junk Hickok. Low starting bid, but this thing will likely climb over $5k, maybe even $10k. Maybe make the seller an offer and see if he'll end the auction early.

Thank you!

Just wanted to say putting an avatar pic of tubes with no markings is a bad showing on your part.

Correct me if I`m wrong, heated tubes are not essential in the testing process of this tester?

I'm sure it's something simple. Would you expect any GE product to work correctly right out of the box? Picky, picky.

Bangy Bang must have switched to a water-based ink that rubs off easily.

I finally found a Mitcham 58 square getter ECC82, BUT it is featured with lush carpeting and obscenely overpriced.

They even started including testing numbers, but make no mention what the tester is, only minimum 45 minimum. Agreed with the $3 coupon, what a deal!
