[drakelist] 6HS6 replacement/equivalent
[EMAIL PROTECTED] made an utterance to the drakelist gang -- hi, I find myself with only 2 good 6HS6 spares - just wondering if there are replacements or equivalents for this tube or should I look for 6HS6 only. This is for my R-4B.

Re: [drakelist] 6HS6 replacement/equivalent
The following tubes may be used as a Good substitute for a 6HS6 but NOT as an exact substitute. 6AG5 6AU6 6BA6 6CB6 My advice...Locate some more 6HS6 units. 73, Jay/AF2C At 02:43 PM 12/11/05 -0500, you wrote: [EMAIL PROTECTED] made an utterance to the drakelist gang -- hi, I find myself with only 2 good 6HS6 spares - just wondering if there are replacements or equivalents for this tube or should I look for 6HS6 only.

Re: [drakelist] 6HS6 replacement/equivalent
Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Jason - Unfortunately, there isn't a good substitute for the 6HS6. The 6AU6A will work, but it's only about half the transconductance (gain) of the 6HS6. This can cause some difficulties with AGC and gain distribution in the receiver. They ARE getting expensive, probably a combination of their unique capabilities and small production quantities. The good news is that they are pretty reliable and long lived. I've only had to replace two over the years, one with an open filament and one that was just flat. One or two good spares, preferably RCA or Sylvania branded, will probably outlast the rest of the receiver and/or it's use to you. In a pinch, you can sub a 6AU6A, but 6HS6s aren't going to get any cheaper or more available! 73, Garey - K4OAH Atlanta Drake C-Line Service Manual http://www.k4oah.com [EMAIL PROTECTED] wrote: [EMAIL PROTECTED] made an utterance to the drakelist gang -- hi, I find myself with only 2 good 6HS6 spares - just wondering if there are replacements or equivalents for this tube or should I look for 6HS6 only.

Re: [drakelist] 6HS6 replacement/equivalent
Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Jay - Have you actually used any of those subs in an R-4B or other receiver? I'm curious, because I've not had much luck with any of them. In the Premixer stage they all give a slightly lower output but aren't too bad, but in the First Mixer the gain and AGC characteristics are altered significantly. Based on my experience, I would consider them fair subs at best! :-) 73, Garey - K4OAH Atlanta Drake C-Line Service Manual http://www.k4oah.com [EMAIL PROTECTED] wrote: The following tubes may be used as a Good substitute for a 6HS6 but *NOT* as an exact substitute. 6AG5 6AU6 6BA6 6CB6 My advice...Locate some more 6HS6 units. 73, Jay/AF2C At 02:43 PM 12/11/05 -0500, you wrote: [EMAIL PROTECTED] made an utterance to the drakelist gang -- hi, I find myself with only 2 good 6HS6 spares - just wondering if there are replacements or equivalents for this tube or should I look for 6HS6 only.

Re: [drakelist] 6HS6 replacement/equivalent
Garey - It's a matter of semantics. :-)) I usually rate them as EXACT, GOOD or Doesn't Exist. In a pinch, the substitutes listed will work, but certainly not as well as the 6HS6 which is far superior than the subs mentioned. Yes, I have tried them and do work with degraded performance...I'm an old tube swapper from way back. ;-) I have never seen a 6HS6 bite the dust. Again, just to feel safe, buy a spare or two...As I stated in my original message. I'm kinda partial to Sylvania, Mullard and Amperex. 73, Jay/AF2C At 04:04 PM 12/11/05 -0500, you wrote: Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Jay - Have you actually used any of those subs in an R-4B or other receiver?

Re: [drakelist] 6HS6 replacement/equivalent
Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Jay - OK, we agree I've only see two fail in the last 40+ years working with Drakes. One open filament and one just about no emission. There wasn't anything rattling around in the latter one, so don't really know what happened to it. It's the only modern tube that I recall going that dead and still have a lit filament! :-) I wonder if Heath had similar good luck with them.? Guess they were designed to run all day in a very hot TV set, so an R-4(any) was probably a vacation. Certainly a more reliable tube than the 6EJ7 !! 73, Garey - K4OAH Atlanta Drake C-Line Service Manual http://www.k4oah.com [EMAIL PROTECTED] wrote: Garey - It's a matter of semantics. :-)) I usually rate them as EXACT, GOOD or Doesn't Exist.
