You say you got the manual with the amplifier, right.No idea about printing this out, but that'd be a very good idea. Best advice is to follow directions. Don't get in a hurry, and don't hold the key down for long periods of time -during- tune up. I didn't read all of the manual so can't give any specific figures for drive or output. Do not expect anything close to 1kw in AM. And lastly, that thing can make you graveyard dead very easily! Be careful. When they talk about not taking the lid off of it, they are very serious. - 'DocClick to expand. Did you flip both switches when you turned it on.http://eco-region31.ru/bosch-profimixx-46-manual If you only turned on the amplifier it was probably a grid to filament short. However, if you flipped both switches, in addition to the tube you may have blown the protection fuse for the HV (no red light). I believe it is a.82 ohm 2 watt resistor. Let us know what you find, good luck. 73Click to expand. The manual contains all the informaton for output and drive. 73I don't know what I was thinking, although it has been about 10 years since I've owned an L4-B. Nevertheless, both lights (yellow and red) should light up (could be a bulb if they don't), read up on the operation of the lights in the manual for the amplifier. The red switch lowers the high voltage level for tuning and when operating CW. For the 3-500z, I really don't recommend used tubes unless it is someone you trust and know will guarantee them. I know if I am selling used 3-500's I will usually not offer any guarantee, just because they don't store very well. It sounds as though you have a filament to grid short on the one tube. Did you contact the guy who sold you the amp. You might be able to cut a deal with him, maybe get him to pay for one half of a new pair of tubes. The L4-B is a great amp, the RF deck is one of the best ever built. It certainly is worth putting the money into, and yes you can mix the Z and ZG tubes but it is better to run a matched pair. 73 Good luckDo you have high voltage gloves.Have you a tube tester or can you get to one.This is by no means a definitive test.If you were (I may be going out on a limb here) but I feel you would be going about this in a totally different manner. (logically) 4) resistors (if sized properly) dont just blow or destroy them selves for no reason. There might be another problem in the amp but you arent taking time or precautions to look for it. You pointed your finger right away to the tubes and then right away again to the power supply.http://esdara.com/images/c5300-manual.pdf I mean no disrespect but if you point your finger at everything at some point you will by the law of averages point at the problem.

My suppliers keep telling me that caps may arrive any day but realistically it could be weeks up to months before I have any caps back in stock. I am doing the best I can to find alternate suppliers with quality capacitors but they are hard to find right now and I will not use the knock-off caps sold on the auction sites.

We believe this power transformer was also used in the later CLIPPERTON QRO For photos see Dennis's (N9AD) installation photos.The stock unit was not a 2.5KVA unit nor did it weigh 35 lbs (it weighs 23 lbs.). Special thanks to Steve - KD8ZBG for reporting this.https://www.temsilcisitesi.com/wp-content/plugins/formcraft/file-upload/server/content/files/1629b369c50fd0---Cost-to-repair-a-manual-transmission.pdf The problem with this design is the plastic to metal junction at the steel collar, which attaches the wheel to the motor shaft. Over the years, the plastic becomes brittle. As a fractured wheel rotates, it wobbles, further stressing the junction until something actually breaks. Unfortunately, no amount of plastic welding or glueing will permanently solve the problem and repairs can cause an imbalance in the wheel that can lead to other problems. The blower motor in my L4B is a General Electric Model 5K3M59ASxxxxx (where x is the serial number). If the sleeve bearings are oiled at least once a year with a good quality lubricant (such as Labelle 107), this motor can last almost forever and with a proper blower wheel, can supply all the cooling the L4B needs in Amateur Radio service. So having a good replacement option for the blower wheel was my best solution. Venturi Plate Figure 2 2 It helps to know something about the design of the blower assembly before working on it. For the purpose of this article, I'll refer to the escutcheon as a Venturi Plate. Both wheels are of the AA design, which is throughly explained on the company website. One was made of steel, was slightly narrower in depth than the original, but had more blades and the correct bore size. It is interesting to note that a replacement wheel from Drake cost 50 cents, which was a fraction of the cost for just one of these new wheels. Figure 3 Figure 4 3 Figure 5 Narrower in width than original but with more blades. Larger wheel presented fitment problems with the venturi plate. Bore reduction sleeve. The wider wheel increased airflow somewhat, over the smaller steel wheel, but the extra depth and bore size presented fitment problems that had to be resolved. Additionally, the thin aluminum wheel and blades were prone to warping if mishandled. The insertion of the bore sleeve caused the rear plate to bend slightly which made fitment problematic.http://www.inhd.com.br/wp-content/plugins/formcraft/file-upload/server/content/files/1629b36a2e91a3---cost-to-rebuild-a-manual-transmission.pdf The extra width of the aluminum blower wheel is not really needed unless you plan to operate a lot of RTTY. If so, adding an extra fan(s) on top of the 3-500Zs to exhaust the hot air would be a preferred solution. 4 Installation: Installing the steel blower wheel is fairly straight forward if you follow these steps: Step 1 Remove the Venturi Plate and set aside. You may have to cut down the Allen wrench to fit inside the wheel to gain access to the set screw. Remove the blower wheel by grasping the steel collar with a suitable pair of pliers. Applying a small amount of penetrating oil (WD-40 for example) between the inside collar and motor shaft and letting it soak in, will ease removal of the collar. Don't yank on the collar as it may cause damage to the blower motor. Step 3 Clean the inside of the blower housing and inspect the motor shaft, which should be smooth to the touch. Correct any problems found before installing the new blower wheel. Step 4 Unscrew the set screw in the new blower wheel just enough to clear it from the wheel bore, then slide the new wheel into place on the motor shaft. Step 5 Position the wheel as close to the amplifier's rear panel as possible, so that the wheel centers in the blower housing, as viewed from the bottom of the amplifier. It is not critical that the wheel be perfectly centered. (Notice RTV sealer where blower housing meets amplifier chassis) 5 Step 6 Tighten the set screw just enough to secure the wheel to the motor shaft. One set screw is sufficient to secure the wheel to the motor shaft. Step 7 Install the Venturi Plate and inspect the installation to ensure that there is no interference between the wheel and the Venturi Plate. Inspect the blower housing where it vents into the bottom of the amplifier chassis. Applying clear RTV sealer around the blower housing will seal any potential air leaks. Step 8 Inspect the sealing tape on the bottom cover of the amplifier and replace if necessary.www.erdilveteriner.com/files/canadian-forces-training-manuals.pdf Sealing the underside of the tube compartment greatly increases airflow past the tubes. Button everything up, plug it in and enjoy your amplifier. In Conclusion: The final installation is neat and professional in appearance and with just minor servicing of the blower motor and an occasional cleaning, your amplifier should perform as the original designers intended.
