I can't wait for the next exciting episode of The '59 Vibrolux. I'm doing some R&R on my old beater '56 Deluxe and this video is helpful. All of Lyle's videos are very helpful for us DIYer's. I've been learning a lot from these videos, excellent work is found here. This guy knows his stuff. I'm going through all my old pre CBS amps and I'm doing what Lyle says.
Really enjoying the videos. Thank you for sharing your knowledge. I know from watching that you prefer the F & T filter caps. In this video you allude to the coupling caps being Jupiters and not being particularly impressed with them. I’m wondering if you could give us more of an idea of your preferences as far as coupling caps with so many on the market, such as Orange Drops, Sozos, Mallory, etc. Thanks!
Tangled-up meter probes? Maybe some day we'll see wireless probes that connect to the meter via wifi..... Probably not very practical to design and likely way more complex and failure prone than we'd like. There's nothing worse than banging your head against the wall trying to diagnose a defective amp and finally realizing that your test equipment is malfunctioning or has bad leads.....
Just found this channel. Great stuff! Wish I had your skills to figure out my issue on my Vibrolux Tweed clone (Mojotone). High Depth (9+), cuts off vibrato totally.
Thanks! I would suspect a bad Depth pot. Wiper losing contact at that end of the trace. To test, turn it up as high as it goes while still having vibrato, then shunt pins 2 and 3 (center and right) of the pot. If you still have vibrato, it's almost gotta be the pot.
@@PsionicAudio Thats the first thing I tried, on suggestion from the Mojotone guys. Pot replaced. No change. (250k CTS). So odd. So now Im just poking around, hoping to get lucky on a bad/cold solder joint. And appreciate the reply! I know you're very busy.
On my Princeton non reverb a JJ tube made the tremolo tick, I replaced the tube with something else and the ticking went away. I also find JJ to be "hard" and lacking in tonally flat and uninspiring.
Old tubes. Colour me not-surprised. The most common vintage guitar tubes - 6L6, 6V6, 12AX7, 12AY7, 12AT7, EL84, EL34 - have been thoroughly picked over so a LOT of the vintage glass for sale is just junk.
Those Atoms were actually very good caps when they were new. According to the date codes they were manufactured in 1992. I. Relieve this well before they became Hollywood Western Town-ized. So, yes, it’s time to replace them with F&Ts.
You have to find a vendor that thoroughly tests old stock tubes at operating voltages and has a no questions asked return policy. eBay is not the place for that.
You’ve got that right. Smaller vendors like KCA NoS tubes thoroughly test and warranty. I don’t even buy NOS tubes anymore. The hassle and expense don’t eclipse any perceived tonal bennies.
Due to previous poor experience I haven’t done business with eBay for years! I refuse to take the chances and wasting my time. Go with trusted stateside sources.
@@luthiervandros I buy from Mike at KCA or Tube Depot specifically. The amp has to be real special these days to get a set of NOS tubes. The only old stock tube I consistently buy are 5751’s and they’re usually used.
Rubber grommets under the tube sockets? How long did fender do that? Don't they create an iffy ground? For reliability, wouldn't it be better to just remove the grommets?
