6BG6 To 6L6/7027A
Requires NO Equipment
Due to the high prices of US made 6L6's, these are starting to sell
fast! I will be raising the price again soon to reflect that so
if you are thinking about buying some, get the now before the price
goes up again.
Do you use 6L6's or
7027A's? Do you like American made ones but don't like the
price of $65 or more? Then you need
to CHECK THIS OUT!
We have procured a VERY large supply of new
old stock Philips/ECG
(formerly Sylvania) 6BG6GA tubes that are PERFECT replacements for any
7027A. In cases where the amplifier connects the cathode to G3
grid), you can even use these in place of EL34/6CA7 tubes. (I am
them in my Eico HF-89 amplifier and Bogen MA-265 amplifier). These
improved 6BG6GA tubes are ABSOLUTELY IDENTICAL to the Sylvania
7027A/6L6GC because they were made with exactly the same
components. They have the larger 35 watt plates found in only the
7581A/6L6GC or 7027A which means they will work in ANY 6L6 or 7027A
application. The difference between the 6L6 and this 6BG6GA is
the 6BG6 has the plate connection at the top of the tube, so it has a
"cap". Because the plate connection is at the top, this
tube can easily handle plate voltages in the 700Volt range. There are
also 2 wires reversed in the tube base. Ok what is
the advantage? PRICE!! While new 7027A's are $45+ each and
6L6GC's are $65 each (or more), our 6BG6GA's
are only $12 each!! We are offering adapter kits to convert
or 7027A's for only $10 each (they only differ in the way they are
You simply plug the adapter into the tube socket on your amplifier and
in the 6BG6. These work and sound EXACTLY like Phillips/Sylvania
We have already sold quite a few of these and almost everyone who has
them has reordered more of them. With the supply of NOS tubes
at an alarming rate, you can still afford to lay in a lifetime supply
I've been asked this one allot. I set the
Philips/ECG tube up on
my General Radio Vacuum Tube Bridge. I cranked the power supplies
run the tube at maximum ratings..(500VDC plate voltage, 75ma plate
Screen voltage was set at 450 VDC. I allowed the tube to run
for several hours. There were no red spots on the plate and the
operated absolutely normally. I did this for several samples. I
the tube up to run maximum screen dissipation (5W). No
then tried several different NOS 6BG6GA's from the 60's. The all
IMMEDIATELY had large red spots on the plates AND FAILED within
Furthermore, I have been running these tubes in my own personal
One is a Bogen 65W per channel amp which was designed to use
It runs 540V on the plate. These tubes have been running for
hundred hours in this amp with absolutely no problems at all.
Can I use the older 6BG6's that I
have on hand already? The answer is MAYBE. If you use
them in an application that calls for earlier versions of the 6L6,(6L6,
6L6GA, 6L6GB, 6L6WGB, 5881), then they will work fine. I do
not recommend the older tubes for amps that call for
6L6GC/7581A/7027A. These older 6BG6GA's have 19 watt plates and
will not work for these tubes.
How do they sound? Well, I
can just tell you that since the internal structure is identical to the
Sylvania STR (6L6GC/7581A), they will sound exactly like them.
How much taller are they?
Well the adapter and cap add about 1 5/8" to the length of a Sylvania
STR/6L6GC. These are tall tubes to begin with, so please be aware
that the overall length of the tube and adapter is 6 inches.
Will I get shocked by the plate cap?
Not really. So long as the insulated cap is in place on the tube,
you shouldn't get shocked. The plate cap supplied is insulated. IF
YOU USE AN UNINSULATED PLATE CAP, THEN DON'T
TOUCH THE PLATE CAP!! THERE ARE LETHAL VOLTAGES PRESENT THERE AND
YOU COULD BE SERIOUSLY INJURED OR KILLED.
How hard is the adapter to make?
Not hard really. You just need to be able to solder some
wires. It will take you about 40 minutes to make each one.
