Hi Charlie ... thanks for the reply. I am waiting on some parts but the standalone conversion is moving along slowly, since I am undecided about replacing the cans with separate caps. All though, that is probably the cheapest way to go!! Your numbers look real good!! I saw a response from...

Hi --- Have a few questions after reading your 440A Mods Thread and looking at your pictures: (1) Is what you are calling the Cathode Bypass Cap actually C93A, the 100MF/100V cap? And is it the BLUE ELECTROLYTIC CAP in your After Mod Picture? (2) How did you arrive at 270 Ohms 20W for the...

Joe --- Did you ever get your 440A amp working in the stand-alone Mode? I ask, because I am looking into what is needed to make my 440A Amp work Standalone. I found a few things on-line that might be of interest to you. The Fisher Consoles Website "www.fisherconsoles.com" has the service...

Hi --- I have recently acquired a Fisher 440A Amplifier from a Custom Electra IV E44 Console and am looking into how to make it a standalone amplifier. Did you complete your Standalone 440A Project and was it successful? Would you be willing to share details of your Modifications? I...

Hi Rich ---- I am also working on a Standalone Version of the Fisher 481A and have a few questions about what you did as shown in your 481A Pictures on Page 2 or 3 of this thread. In your picture showing the Speaker Binding Posts and the "rewired 6-pin Molex" for the speakers: a) How did you...

I recently acquired a VTP-100 which has a Preliminary Manual 1.1 that includes mdelrossi's schematic plus separate PS Schematic. Is the separate PS schematic what you need? I sent you private message over on the Dynaco Tube Forum.

The unit was triple boxed and it was too big to get in my car when I got it from the Post Office since it needed a signature and no one was home, so all I have had time to do is get it out of the big outer box, crush the outer box, so I could get everything into my vehicle. The next few days...

Hi --- Last week I bought a SV VTP-100 on eBay which was delivered this afternoon. Mine has a serial number in the 0708xx number series. When I scanned thru SV Preamp sales on eBay, I discovered that the guy I bought it from had bought the unit from another eBayer on 02/09/2017. Since your...

rudedogg --- did you ever get the SV VTP-100 working? I ask because the Forum Thread just stops in October 2016. Also, what is the Serial Number of your Preamp?

PAD70 Info Hi John --- I looked at your OpAmpBuffer pictures here at AudioKarma. The white capacitor end of the Buffer Board is driven by a single wire from the Quad Cap 20MF Tab (SQUARE or 3-Sided_Rectangle Tab) to the front edge of the Buffer Board next to a resistor. This is the INPUT to...

HTHMAN - Thanks for the detailed info. I ordered two sets of the Minimus 77 foams (the ones Bootapest2 lists as being for 4 & 1/2 to 4 & 3/4 inch speakers). I have the Optimus Pro 77's (non-lineaem tweeter version) which still function OK, so I will hold off on foams for these. Thanks...

Surrounds - Minimus 77 & Optimus Pro 77 HTHMAN -- I know that this is an older thread, but where did you find/get the surrounds for the Minimus 77's and the Optimus Pro 77's??? I ask, because I have a set of both speakers, Please let us know. Thanks in advance!

Hi Terry -- do you work on Fisher 500C's? I have one that sounds very good, except when at the FM Automatic position of the Selector Switch. Don't get a multiplex signal (Stereo Beacon does not light up, but bulb is good), have sound but not multiplex. Sounds good in the FM Stereo and other...
