I really appreciate your clarification about Fender's upselling strategy at the end of the video. Leo "blessed be his name" Fender wanted everyone to own a Twin. He may have been a nice guy(or not), but he wanted as much of the consumer's money as they were willing to give him. He was not interested in giving people "bargains". Cheers, Alan Berlin
Great video on my pair of Princetons Lyle! Always amazed to watch your videos and I appreciate the knowledge, expertise and advice you’ve given me on them!
The kind of mild and very sensible circuit changes you often recommend and implement would only seem to send shocks of outage among the collector/speculator clients (the people who don't actually use these amps). I'm guessing the musicians/players would welcome them. Well done.
I love my 64 handwired reissue. Cost a fortune when I aquired it 4 years ago Has gone up in price over a thousand bucks since then because of Canadian insane inflation My friend modded the tremelo to get it slower for that swampy goodness Sounds great on the stock Jensen and even better on a 12 inch vintage 30 I have in an old cabinet Shouldn’t need service till several years after I’m dead and gone
Pearl Clutcher, LOL, brilliant Im stealing that one! Today Uncle Larry coined "Crushed Mother of Toilet Seat" to describe triangular Rick inlays. 2 in on day. I should play the lottery.
I took inspiration from when you mentioned the reverb node trick a while back in a reissue video. I found it dropped the preamp voltage a good bit, so I decreased the 18k to 12k in the pi filter that feeds the formerly unused node. That put it back fairly close. I then came across Merlin's article on the reverb driver, and changed the 2.2k to 1.5k with the node voltage very near the 350v target he mentions. Additionally I increased the recovery stage cathode cap to 250μF to help with h-k noise (as the standalones did). Reverb is now clean and quiet all the way up to unusable levels. Thanks for the tip!
Watching this after Brad's live stream, as ever really great work especially with with the new cap board and these amps should be good for many years to come. I agree that Leo was always wanting you to upgrade that's why I went through several of his amps ending up with a quad reverb. Just check out only the more expensive amps had metal corner protectors. If you don't post any new videos have a very happy and peaceful Christmas.
Thanks Lyle, appreciate the time you spend making these videos. On moving the reverb supply, would you need to alter the internodal dropping resistor value? Thanks.
You can but I did not on these vintage ones, as it would involve changing still more components. But that would be to increase preamp headroom, doesn’t really affect the reverb driver. Just adding that next stage of decoupling/filtering does the trick.
I would love to own just one Princeton or Deluxe. Had a Deluxe, but traded for a Boogie Mark IIb, Wish I still had the Deluxe. I do have a PRS Texaplex II that has a beautiful Strat sound...just a tad too much bass.Gonna try a ET-65 in my 112 home built Pine cab. Pine sold today ain't the same. Way back when, there was more heartwood in pine, zero in today's pine.
Lyle as always another good video, will you be showing more work you have done in the bathroom and your plumbing? I enjoy all that to dude. Merry Christmas!
Hello Lyle, I am in the market for a combo amp around 3k or less. I currently own a Vibrolux Reverb from 73 and am looking for something a bit more Marshall-esque. I want the ability to have great cleans and I mostly use pedals for OD. Any suggestions? Love the channel, thanks!
On the reverb transformer modification to re-connected to the 320V node, might the reverb driver tube cathode bias resistor be changed to 2.0k or 1.8k ohms to try to maintain a similar bias to the 2.2k/8V of the original circuit? Or is it insignificant?
Another great video, @PsionicAudio. Have you had a chance to work on the '64 handwired Princeton reissue? If so, is it as bad as the '64 Deluxe Reverb, or did they stay more faithful to the original design?
I'm on my third. They sound great, but still have the reverb hum! I run mine through a Brakelite so don't really hear it. I upped the first 2 filter caps to 33uF when I fitted F&T filters which helped, but it's a design flaw.
Yes, a long time ago. They’re very good amps but way overhyped. Carlton’s best tones were a 5E3 Deluxe. SRV sounded amazing on Live at the El Macambo with a Super Reverb and a Vibroverb. They also sounded great with Dumbles, but the amp was just a good amp. It was the player.
Thousand volt or 1 kilovolt. But I said thousand kilovolt…
That’s one hell of a cap 😂
That would be probably a Flux Capacitor.
Only two legs tho
Moar toan
A MILLION VOLTS

Thanks Lyle, great tip on the reverb supply node.
Great to have you back Lyle! Hope the bathroom is finishing soon!

Thank you for including the part # for the cable glands.
Nice work Lyle. They sound just heavenly.

which resistor do you change? the 18k on the cap can?
It's so good to hear real, organic, Tremolo and Reverb; even with the hum!
Thanks for everything you do on this channel!
Thanks for rambling! I'll take your ramblings any day.
Killer amp for surf guitar.
Cool to see and understand technology from the Mesozoic era.
Nice amps I can hear good tone, the tremolo is fantastic and the reverb is yummy

I was having Amp withdrawal. Thanks for posting Sir.
Thank you, Lyle! Great info!
That first amp sounded perfect
Great video!
Very nice work. Soon you'll be called the Amp Whisperer.
He’s back, everyone!
I appreciate the Mouser part number! 👍👍
"Another potential pearl- clutcher" 😅😅😅 missed that one the first time around!
I always tell people that the red turd caps are actually good. Thanks for saying it
Inspiring work!
The best returns
More great work!
Sounds good. Thanks.
I really like the fact that you did away with the Multi can cap ,Beautiful sounding amps
Mahalo Lyle!
Ramble on Lyle !
Calamitous! Don't hear that every day in amp service videos.
Thanks Lyle, appreciate the time you spend making these videos.

Traded for boogie? Criminal offense
I like pearl clutches and couch fainters.
Any improvement kept a bay for the sake of "authenticity" is a way to eventually get an authentic pile of ash.
Lyle as always another good video, will you be showing more work you have done in the bathroom and your plumbing? I enjoy all that to dude. Merry Christmas!
I will soon. Thanks!
Hello Lyle, I am in the market for a combo amp around 3k or less. I currently own a Vibrolux Reverb from 73 and am looking for something a bit more Marshall-esque.

Not a big deal. Notice Fender kept the cathode constant no matter the b+ changes in different models.
I really want a Princeton reverb, unfortunately a classic amp is out of my price range....
A used ‘65 Reissue is always a good bet.
Another great video, @PsionicAudio. Have you had a chance to work on the '64 handwired Princeton reissue? If so, is it as bad as the '64 Deluxe Reverb, or did they stay more faithful to the original design?
It’s more faithful but way overpriced for what you get. Only possibly justifiable on the used market. jmtc
I'm on my third. They sound great, but still have the reverb hum! I run mine through a Brakelite so don't really hear it. I upped the first 2 filter caps to 33uF when I fitted F&T filters which helped, but it's a design flaw.
I was just wondering how things were going Psion way.
around 2 minute what are the little lumps of brown lying on the board ? look like maybe capacitor casing ?
Little bits that flaked off the old ceramic disc caps in the LFO.
@@PsionicAudio nice sharp pictures, great sound and work, thank you
That's only a megavolt it would make me tremolo
Lyle, why do they spec 1kv caps for the tremolo circuit?
Fender used 500V caps. I like the extra headroom.
How long are the standoffs for the filter caps board ? thanx
1/2” is what I used.
have you ever worked on a dumble ????? are they really as good as i have heard or just rich boy amps ????
Yes, a long time ago. They’re very good amps but way overhyped. Carlton’s best tones were a 5E3 Deluxe. SRV sounded amazing on Live at the El Macambo with a Super Reverb and a Vibroverb.
They also sounded great with Dumbles, but the amp was just a good amp. It was the player.
@@PsionicAudio thank you sir !!!!! your advise has saved me tons on piss poor amps
I was going to thank you for not using that auto-zoom but then I noticed it started up at 4:40...so I stopped watching.
