Deluxe Reverbs and holding out for the right one

Deluxe Reverbs and holding out for the right one

Postby Banana Boat » Thu Jun 06, 2013 12:59 pm

Hey all,

Ok got the sms and mc250 for home jamming.
I need....well would like... a travelling jerry combo.
So as far as a Silverface Deluxe Reverb I want a pre 74 cuz of the push pull pot...right?
If one does not use the push pull on a >74 does it sound the same as a <74.
Actually I want a 1970 cuz that when I was born....right???
Now I am aware of the power amp tap on the 79-80's....neat...right..
Ive got an extra E or K to throw in.
Ive read comments from one of our gurus that says a 79 with a K is a dream...
Ive passed on a several reasonably priced 77's, 78's that were near mint!!! thinkin I shoulda jumped!!!
Problem here is that ive read too much on this and am now thoroughly confused.

Looking for some Kind light here..the kind that sheds....haha...

Thanks all,

Merle

Get a '68 drip-edge. Blackface in a silverface shell.
Bought mine with a D120.
Change it to the Super-Sarno tone stack.

Love mine. Breaks up & gets creamy at a low volume. Tons of Jerry in there.

Only issue...JBL makes it a brick to carry.
Peace

I've also been looking into a 1x12 grab and go Jerry style combo. I've been narrowing in on an older model Deluxe Reverb silverface as well. If anyone has Audio/video of playing jerry style through a DR of any vintage I'd love to hear it.

Cosmetic silverface but blackface circuit? hmm... Is the blackface circuit more desirable?
Does that mean that Jerry mods to a silverface starts with a blackfacing?

Yessirr.

Jerry used the Blackface twins exclusively. When it wasn't a Blackface, it was a Silverface drip-edge with a Blackface circuit (as mentioned above)

along with all the post alembic mods on my website. here are a couple more options in turning a deluxe into a small Jerrified combo. makes for a great preamp as well with some of the mods below.

change the rectifier to solid state.
change the output transformer to handle 6l6's.
change to 6l6 power tubes(or kt88's for more headroom) rebias accordingly.
change the filter capacitor can to ab763 specs.
remove input jack 2 and only use input 1, slide the volume pot into input 2 and bass pot over to where the volume was and insert a middle potentiometer(use the twin layout/schem).
change the speaker to a k or e 120.

Waldo My Man!

That sounds really fun! I've been seriously considering the 6L6 Mod. I like that rectifier Mod too. I've been toying the 5U4 and the GZ tube, but there is abundandant debate about the consequences to plate voltage. Most of it is over my pay grade...but someday...I'll get it all stored up there.

Always appreciated.

I'd be using the SMS+Mac for gigs and a Deluxe at home but TEHO, YMMV, etc.

Waldo,
Thank you so much for your hard work and contributions to this community! I love the idea of turning my deluxe reverb into a jerry combo. If I already had the speaker, how much dough do you think all those mods would/should cost? ballpark. Thank you once again.

So far the blackfacing + the post alembic mods cost around $160.
DNI preamp tap or waldo's tips above
This includes everything else plus shipping and a $30 gz34 rect. tube.
The tantalum cathode caps were close to $10 each and haven't put them in yet cause they take about a week longer to ship.
Comes from UK... customs thing.
You're either building a bomb or doing Jerry mods with these things I guess.
Took this unskilled solderer about 10hrs.

Btw... anybody have ab763 filter cap values?

typically 250pf, .1uf, and .047uf (from the ab763 schematic)... I believe in the trem channel of Jerry's twins (according to Waldo's schematic notes) the two larger caps were changed to sprague orange drop 225p .022uf.

:lol: :roll: :lol:


TVA1620-E3 x 2 = 100uF 350volts
TVA1906 x 3 = 20uF 500V
TVA1346-E3 x 1 = 100uF 100volts (Bias Capacitor)

Add 75- to all 3 for the mouser part number.

I just scored a 1964 FEIC Princeton which was modded to 6L6's back in 1985-ish by VA (Fryette, Conrad, or Rivera likely did work) and it is just fantastic. I also have a 64 FEIC Tremolux which is an AB763 with 6L6's rather than the 6V6's. The Bandmaster has some years of AB763 with solid state rectifier, and its a head which is good for lugging (so is Tremolux). The Deluxe non-verb stopped in '64 but I would look at those to, much less dough sometimes and good reverbs are around (even if they do take time to find :) I have a Fuchs (local guy here) pedal digital that does a nice plate/spring thing with decay pot too that goes into delay land.

I have later SF Princeton and Princeton Reverbs which arent sublime by any means. I think the cabinet wood being changed to particle board with glued baffle (like a bass cab) is as big of a difference as any other CBS mods in the small amps. My 64 just has a totally different presence than my 78 Princeton. I am not sure if the Deluxe began coming in particle board, but it would likely have been in 72 if so (I would guess yes). The master volume models are easy to spot by the extra pot, but that in and of itself is not a big deal...other mods that came about the same time on bigger amps are generally more ostracized and hard/impossible to undo I think.

I have never owned one, but always wished I did. I think that the Deluxe Reverbs might just be the best amps ever made. Played thru several, and they were all great, even the master volume ones. Even without any mods, they are great amps. You can buy any Deluxe, mod it to suit and it would be great. Just my 2 cents.
