5y3 vs 5u4. If you know someone with a spare 5U4 tube, try it and if it does the same thing, time for a new power filter capacitor. The recommended bias setting for the ST120 tubes is 50 mA each for a total of 200mA Using a rectifier which requires higher filament current than the rectifier your amp was designed for, pose a potential risk of power transformer overheating. Also, 5U4 has a little less forward voltage drop While a 5Y3 can support a pair of 6V6s and a few preamp tubes, it will sound a bit ‘fuzzier’ or 'spongier' you might not lose as much B+ voltage as you think (because the 5Y3 draws To investigate this, I conducted a series of tests using a flexible amplifier circuit designed for a 5U4 rectifier, allowing for direct comparison with I have found the voltage drops listed to be a pretty accurate rule of thumb. (A new-looking 5Z4 I once tried committed suicide With 5Y3, 5U4, and related types, the filaments of the rectifiers comes up to temperature in just a few seconds and B+ comes up. The 5U4G is rated for less current draw vs. So they will function in each This means you can generally put a 5U4 or 5Y3 in an amp that had a 5AR4, but it is not recommended to put a 5AR4 or 5U4 in an amp that had a I was thinking of a 5F2a with a 6L6 instead of the 6V6 power tube. Another build on this forum went in this direction but used a 5881 power tube. " Comparing charts between the 5Z4 and 5Y3, they do seem to imply the 5Z4 has slightly less internal Admiral 19A1 5U4 vs 5Y3 #1 &bullet; OP &bullet; Jul Mon 23, 2012 1:48 pm This is a question regarding the popular Admiral 7" TV Sammy says under a section labeled Production for 5U4 and 5Y3 tubes. In most applications, you can swap them for each other, at least for a quick test. 🙂 The #80 and 5Y3 are electrically equivalent. A 5U4 will replace 5Y3 if the power transformer can supply the extra current without over Who is online Users browsing this forum: No registered users and 1 guest The 5U4 has a B+ higher current output than a 5Y3 so if the radio, amp or whatever calls for a 5U4, it was probably because of its B+ current demands. The 5U4GB is a directly heated dual diode. Octal. Chances are yes, the 5U4 is going to You can use a 5u4GB as it is rated at 275mA. The 5U4 (filament rectifier w/comparitively high voltage drop) should actually drop more B+ volts under load than the 5AR4 (cathode-type rectifier with comparitively low voltage drop), I like warm sound of Brimar 5R4GY 2 x O getter very much. com Tube# - Base - Fvolt - Famp - Vdrop - MaxPmA 5R4 rectifiers (any suffix, GY, GA, GB, GYB, etc) are pin compatible with 5Y3, 5U4, 5V4 and 5AR4/GZ34 rectifiers. 1K subscribers Subscribe rectifier tube performance test ; 5R4 5U4 5Y3 5AR4, using 300B SE tube amplifier right sound 14K subscribers Subscribe TUBE RECTIFIERS DATA – QUICK SHEET 5Y3 / 5Y3G – FIL : 5V, 2. 5U4 has higher AC current draw ( 3A vs 2A for 5y3) and gives better bass performance IMO. there's a lot of info out there, but some sites contradict each other on this- some say 5z3 and others say 5z4 for instance.

Our 5Y3 / 5Z3 Rectifier Tubes have a reliable response with a average sag & longer than normal life expectancy and offer a great dynamic response sound. They produce a similar voltage drop to 5U4 rectifiers but require only 2 amps You are in luck. Solid State 5U4 5Y3 etc. www. If you look at a tube data book on the 5U4 vs. The difference lies in the basing/socket, UX4 vs. It will have less voltage drop than the 5Y3 but also draws an extra ampere from the 5v winding (as you found out). I’m looking at ShuGuang WE274B tubes which list as replacements for 5AR4 / 5U4G / 274B. Chances are yes, the 5U4 is going to Is there much difference between 5Y3 and 5U4 rectifier tubes. Seems the 5U4 was a bit of "overkill" 5Y3: Most commonly found in American amps of 20 watts or less, such as the tweed Deluxe and its derivatives, the Princeton, and others. To investigate this, I conducted a series of tests using a flexible amplifier circuit designed for a 5U4 rectifier, allowing for direct comparison with Is there much difference between 5Y3 and 5U4 rectifier tubes.

I have a Primaluna Prologue 3 which uses 5AR4 rectifier tubes which id like to roll. By having this information on a chart you can choose a rectifier tube that will best suit your playing style. The 5y3 family of tubes sound a little too mellow for my test. A 5U4 is a bigger tube (physically and electrically) than the 5Y3. (A new-looking 5Z4 I once tried committed suicide I was playing musical rectifiers today, swapping tubes among my radios. I got good suggestions about that, for which I thank everyone. Fourwater. With the rest of the tubes still cold, this surge trying to get info on the direct equivalents to a 5y3 rectifier tube. I am wondering if a 5Y3 will run one I recently restored a Western Air Patrol radio. It seems to me that the 5U4 was used more on high powered audio amps, making me think that they can handle more I have settled on Russian NOS 5U4. UX4 socket out and Octal The diodes handle most of the current load, yet you still get sag, in fact with this you can run a 5Y3 where only a 5AR4 or 5U4 could be used current load wise. Ads are not permitted. My Airline 62-311 wants a 5Z4 but had a 5U4GB installed. 3 amp 5U4) the 5V4 actually has less sag than the Looking for the most sag in my tube amp.

I believe the plate resistance of a 5Y3 is quite a bit higher, and the dissipation is of course lower. Perfect for getting more headroom and stability out of the amp! Hi jarthel, I like the 5AR4 for its built in slow startup and very low voltage drop (read: more efficient). That schematic calls for a 5Z4 rectifier but it came with a 5Y3 The 5R4 is perfectly acceptable. 5AX4-5U4 RECEIVING TUBE SUBSTITUTIONS TUBE 5AX4 (contd. 5Y3, . Now I believe this is not per definition a GEC U52 trait (maybe Dubstep girl can chime in here), but maybe more a case 真空管 - 整流管 Rectifier Tube 並非所有的管機都需要整流管。 雖然利用真空管整流，才算是血統純正，才最有管味 (音質的確較細膩、柔順)， 但基於便利性、成本、噪訊等原因，許多管機採用二極體 I was playing musical rectifiers today, swapping tubes among my radios. A 5W4 has about the same specs as a 5Y3, but will drop a few more The 5U4 wants a whole amp more filament current (3A as opposed to 2A for the 5Y3), so I'd watch your PT for overheating if you're gonna try it. ) SUB. So, other than amp draw (2 amp 5V4 vs. Hey, I'm referring to the most modern vintage versions here (GT; glass tube, if you like). I never did find the correct schematic but did find one that was close. i have a cust What is the B+ voltage currently?
