Checking Out This Tweed Deluxe Clone | Rift Midweek Update + Q&A

[@markcarter1118]

Would definitely like to see a 5F1 build….

What do you think about using a switched power supply (as in the new Black star 100W amp) in order to significantly reduce the weight of an amp/combo? You can probably even make the voltage adjustable and more or less stable .... ? Win - win - win?

[@DornAndGrant]

Utter admiration for your and aynsley approach to signature amp quality.

[@giulioluzzardi7632]

What does the pot next to the Rectifier valve do on the Dlux combo?If you told us I missed it, keep up sterling work!

[@RiftAmps]

VVR 👍

I think that a Princeton retrofitted with a Deluxe Reverb power transformer is the original modification that Randall Smith made that led to Mesa Boogie.

As the owner of a 76 JMP 2203, its really interesting watching these little 1-watt JCM800s come along!

[@martinreid1740]

Another interesting video, thanks for posting it. Looking forwards to hearing the one watter.

Zack Drummond built Eli's cabs

[@RiftAmps]

Yup, Zac made some killer hardwood cabs too

Hello! Got a question: I am having a hard time dialing in my solder station. It’s either too little heat or too much heat. What do you usually set your solder station for eyelets, turrets, and chassis grounds?

[@Jules-hi7xm]

Is the mains safety earth on the Abbot Deluxe clone looped off a crimp tag on the standby switch and then onto a transformer bolt? That's a bit amateur if so!

[@hannowirth7245]

You can run a Deluxe non reverb with a 5U4GB, that will reduce voltages.

[@RiftAmps]

only if the 5v winding is rated for 3A...not all were.

[@hannowirth7245]

Yes, but Fender used the same PT for both Rectifier Valves( 125P33A)

[@RiftAmps]

@hannowirth7245 not all P33As have a 3A winding...that's my point, the spec changed over the years. I have a customer who found out the hard way!

[@Mark5mith]

What are your thoughts on the new mesa boogie, and why would they use a dual rectifier? Really enjoy your work in the black magic of valve amplification.

I regret not grabbing one of the Black Friday specials, I did find a second hand mint factory built Mojotone Studio One for about 300 pounds which has a JCM800 or 5e3 pre going into 1 watt single tube a/b output stage (no inverter tube). It is a load of fun with a greenback. Mojotone also sell a hotrodded 5e3 that I snagged as well.

Hi Chris. Happy New Year. Another great video as always. As you pointed out the deluxe clone has a pretty high 150hz 3rd harmonic of our 50hz mains frequency. I couldn't tell from the video and Apologies if you have tried changing the 6V6's but I noticed the ones in it are TAD and I had a genuine Fender Tweed Deluxe in for service about 12 mths ago which also had the 150hz hum and the output was down. I couldn't find anything abnormal or out of spec components including the transformers and the valves all tested good too, however I decided to swap the TAD output valves for another matched known good pair of mine and that cured it. No more 150hz hum and output to a nice healthy level. Why both valves tested good when clearly they had become faulty I don't understand? I doubt it will the same problem with the one you have but as I said if you haven't swapped the valves might be worth a shot. PS I think I put Sovtecs in it.

I'm actually building an amp with a very similar output stage to the 5e3 and see the same crossover distortion on my scope as you showed in this video. How much crossover dist is normal/acceptable for a 5e3? My 6V6 plate voltage is at about 385VDC ,should I lower it? There is almost no real clean headroom, but always some grittyness even at very low gain. If I move my signal generator to the PI there is still some grit. Any advice?

[@marktierney3938]

You probably already know this but on a 5e3 if you plug into the bright channel and gradually turn the volume up on the unused normal channel you should get a bit more clean headroom. There is a sweet spot.

[@hakonmoen3438]

@@marktierney3938 thanks for the tip, but my amp is not a ture 5e3 and only has one input. Also the output stage has crossover distortion at very low levels entering the LTP phase inverter. I might need to consult some forum experts at this point :)
