    68 II looks like the right schematic.

    Official Ampeg Portaflex Club

    Completed the cap replacement of the B-15N amp this weekend. BTW the amp matched the 1968 schematic. Also - changed the diode and caps on the board (but they seemed ok). It’s closed up now and doing fine. Still a little noise on channel 2 but nothing bad at normal volumes (if I get ambitious...

    Tested the p resistors in circuit and they read ok.

    PS I thought channel 2 sounded a little better than 1 (more natural) w music playing the B15; similar tone and volume setting. Best “music” tone interestingly was with both ultra low and high engaged in the normal channel on both 1 and 2.

    Official Ampeg Portaflex Club

    Thanks again for all the advice. After replacing the electrolytic caps and putting shrink wrap on the transformer leads, fired up the amp to do a quick check. Channel one is pretty quite, channel 2 has some hum as the volume is turned up, but I would not push the cabinet much above where you can...

    There is a diode tester on the multimeter. Without power on the amp, the diode reads 0 or .5V depending on which direction I have the tester leads. The 0.513v read was with the black lead at the ->| end of the diode. I will likely replace it either way.

    Beans, thanks again for your help and support. The multi-can is well isolated w a spacer. I had a spacer in my parts bin plus FlipTop sent one for the new can. The serial number stamped on the chassis is 090071. Pot code date = 1969. The sechematic I’m following (seems closest) is labeled...

    Official Ampeg Portaflex Club

    Beans, I’m began working on my B15N; the diode on the board is marked F8 (there is no schematic left but one that looks closest from the net lists F4 as the part). It doesn’t looked damaged but I’m not sure how to test. Should I replace and if yes, what is the best replacement part? Fliptops...

    Calling on the Portaflex Club for a technical question. My 70s B15N was gone over a few years ago by a tech in PA (when I lived in the Philadelphia area). He changed a couple of caps and did the 3 prong plug conversion. I am getting ready to recap the electrolytic caps (purchased from...

    Official Virtual AMPEG Portaflex Club, Part II

    Hi Portaflex Club. I would like to join but only have pictures of the insides of the amp while I working on mine. It's a Black Tolex 70's B15N that I've had for about 10 years. I used to have a beautiful Blue Tolex B15N from the 60s but sold it to a friend who wanted it more than me for his...

    I was going through some boxes and found this single unused Gold Maxima .120 string (Maxima Manufacturing Company, Germany). I purchased a 5 string set years ago for a 4 string jazz with gold hardware and just placed this sting to the side. If anyone would like this single "unique" string, I...

    B15N Tube Preamp DI Build Report

    Thanks @sjrash The blues clip was my attempt to show the other end of warmth. SOS tone is a result of the combination of the P-Bass, the flats and the P-15 but agreed the P-15 can do a nice warm B-15 like tone.

    B15N Tube Preamp DI Build Report

    I also got a chance to run the DI/Pre-Amp into a Crest power amp (an older and butt heavy FA-2401 that has tones of power) and it did a great job as a pre-amp. DI out of the P-15 into the DI input of the Crest.

    B15N Tube Preamp DI Build Report

    Some additional clips using the P-15. Sultan's of Swing is a Fender P w TL Jazz Flats, tone slightly rolled off w P-15 tone at noon for B&T. The Blues loop is an active PJ w Round Wound strings to give you an idea of that set-up. I used a slight bit of compression on both clips (3:1) and an EQ...

    "Entry-level" Alembics, how are they?

    Had a Spoiler (Zebrawood top) that I loved. It was stolen but wish I still had it. I thought the 32 inch scale was perfect.

    B15N Tube Preamp DI Build Report

    The sound clip is made with a play along sample of Soul Man. The background noise is in the Soul Man play along file. It doesn't help that my house power is C%@p. Recorded with a passive Fender P Bass (strung with Thomastik Jazz flats) into the P-15. Signal path is: P Bass > P-15 > DI out >...

    B15N Tube Preamp DI Build Report

    Yesterday #3 of 15 was delivered. I have had only a short amount to time to take it for a spin but my initial impressions are that the P-15 far exceeds my expectations! I am lucky to have a B-15 as a reference. I wanted to see if the P-15 from @Azure Skies could provide "that" tone for DAW...

    Want tube sound for live but not the schlep

    Fully agree with @brianrost on the Hughes and Kettner or SWR ISO as a great option. I too use a H&K with a regular cab (8 ohm) for practice at home and surprised at how loud those few watts can be! Clean to OD is possible. I think mine is a blues master version. Personally I like the H&K better...
