I picked up a Marantz 105 tuner recently. It needs all new lamps. What's the best way to access them? Remove the front panel? Go inside?

I'm working on an early 400 that has the fuse style incandescent lamps. I bought blue and warm white fuse style LEDs. The light winding on the transformer is only 6.7 VAC with a line voltage at 120 and the 8 volt LEDs were dim. I considered adding a few turns to the light winding on the...

Up on EBAY. Loftech TS1. I've been using one for 40 years. Awesome all in one, low distortion generator. Somebody jump on it.

I'm workin on a 700II and the 6-32 pem nuts are missing on the lefts ide of the sub panel. I bought some on EBAY and much to my chagrin the holes are stripped out and the pem nuts won't seat. Other than going to an 8-32 on one side is there any other options?

I've got 2 Dranetz 626 power line monitors that I'm tired of looking at. They're available to whoever wants them for the cost of shipping. They're about 25 years old. Worked the last time I turned them on which was about a year ago. You set up some parameters and they spit out numbers if the...

Scored several boxes of tubes from an estate yesterday. Most will likely go up on EBAY.

From time to time I pull fan panels out of the scrap barrel at my day job. Most of them hold 2 x 4" muffin fans. There are also 3 fan panels. The 2 fan panels sit nice behind 400's and 700's. If anybody wants one I'll ship them to a U.S. address for $10 which is the about the cost of...

I enjoy identifying vintage audio gear in movies and TV shows. I've watched all of the Bosch seasons on Amazon. Every once in a while there is a shot of his home music system. The system appears to be a McIntosh 240 amp and a McIntosh preamp, Marantz turntable, and Ohm Walsh speakers. Season...

Anybody seen this? I don't think I've seen this bus wire for the ground nor the soldered connections on the caps.

I have a few different , application specific, soldering irons on the bench. I'm thinking it's time to upgrade and consolidate. I'm looking at this one Pace Iron. This one features easy to change tips. No it's not chepa, but I want an niron that heats up fast and delivers the heat when...

I'm running low on AGX8 fuses. Octopart showed Digikey had the best 100 pc price of about $0.50 each. Before pulling the trigger I tried EBAY and found a vendor that had 100 pcs for $18. Of course there is no telling if these are fakes as as the photo does not show a vendor name. Anyhow they...

A friend recently closed his business and gave me a couple Tektronix 912 scopes. These are basic 2 channel scopes. They make a trace but they have issues, most likely capacitors. I have a Hitachi 222 scope that I loved for 30 years. I broke it out the yesterday intending to give it to a...

Referring to 400's, it has come to my attention that there is a conflict with the mounting of the relay board in conjunction with the White Oak back planes. The conflict involves the location of the decoupling caps on the back planes which must be bent to allow the relay board to be mounted...

After about 6 years of fooling around I finalized a circuit board with a triac to save the Arrow Hart power switch on the 700B's. I listed it on EBAY tonight. Then I searched for it to verify the listing. The first search result surprised me. Here's the link. 700B Power Switch The $90...

Does anybody remeber Tuge God from the early 80's? He had a manual for upgrading clasic tube gear such as Dynaco, Eico etc. I had the manual, can't find it now. I

What is name of the hookup wire that appears to be stranded but the strands do not separate when the insulatioon is stripped off. It is commonly used on smal transformer leads.

Many years ago a friend gave me a 2000II preamp. It's been on the shelf since then. Recently I checked it out to make sure it functioned and permanently loaned it to my brother. It turns out that the volume control doesn't go completely off. It's not some faint music. It's readily audible...

An individual contacted me who was cleaning out his garage. Decades ago he worked in pro sound and used a ton of 400's. He has/had about 75 XPL909's and 20 or more RCA410's/66546 and a smattering of some other transistors, all small quantities. After a few emails I realized he had been a...

A local repair shop changed owners some time ago. In the process I received their Phase Linear file. They must have been an authorized repair center form the beginning base on the documents I've seen. I stumbled across a service bulletin recently that dealt with silpads. Thought I would...

So there is a Hall of Fame A wall of shame (Peru) And my room of Flame (AKA The 70's room) My brother needed an upgrade from his 35 watt Lafayette receiver. I permanently loaned him the 2000, and a 400 I just reworked. I used this as an excuse to pull out all of the P/L gear that somehow...
