I've been reading through the forums for a few weeks now as I work on my project SB-220 and have noticed a few different type of glitch resistors used on the HV side. 20 ohm 20 watt, 10 ohm 10 watt and a few other combinations. I would like to add the glitch resistor to my amp but can only source a 20 ohm 12 watt resistor at the moment unless I go with a cement version which I have seen quite a few recommendations from folks advising against using for safety reasons. Seems like there are a lot of back ordered parts right now at Mouser and Digikey and I am not able to source one from them at the moment. Would that be OK to use the 20 ohm 12 watt for now until I get my 20 ohm 20 watt that's on back order until August? On another note here is what I have done so far - 1. Replaced caps 2. Replaced HV board (with one that come with the amp but needed to be installed) 3. Bias mod (moving wires on the relay) 4. New tubes 5. Replaced the muffin fan with the factory fan 6. Cleaned up some of the wiring Here is what's left - 1. Glitch resistor 2. Return suppressors back to stock (have the resistors on order and they were not out of stock thankfully) 3. Fix the ungrounded RF output cable by replacing it with a longer run) 4. QSK mod (Waiting on backordered parts) 5. Repaint the cabinet So far it's coming out pretty good.
