Hi Group: Does anyone in here own of these mitsubishi or JVC HD tape VCRs? I am thinking about one; I am NOT interested in any sort of hard drive storage...
Thanks Ray and Roger. I am going to try picking up a high impedance (2 kohm) earphone used by crystal radio builders and connect it directly to the line out...
-Hello Garland, The tuners that I have worked on typically had fixed outputs of .3v to .7v and variable outs of 0 to 2X fixed. Out Z varies around 3K to 5K...
RS is having a 50% off sale on parts in their pull out drawers. 100K Alps stereo pots, blue LEDs, lamps for FM tuners, resistors, caps, speaker posts or...
The Sunher Coax you found is a very premium cable. If you have not chopped it up yet its worth a bit on eBay. They are one of the primary suppliers to Agilent...
I know this is an old item but in the interest of reply and passing on old stories what you described is the reverse of how the Koss ESL headphones were...
-Hello Demian, It sure would be interesting to know koss's EQ values. To emulate the "sound" of a speaker you would also have to include the acoustic ...
No I haven't cut it yet, but I confess I had not thought of selling it on ebay. I'll give it some thought. I could use some $$ to finance other audio...
I really like the programming on AM 680 out of Baltimore, MD but can't get it at home (about 40 miles away) or at work (steel and concrete building with lots...

... 80 watts is hardly what I would call a lot of power. Check out the Altec 1570 for power! ... I used to have a pair of them. I traded a pair of them and...
Hello, 80 watts is a lot of power in the tube world IMO. I agree with a LOT you say below except for the 1570s. Don't reget that sale. They may be powerful but...
I have been reading alot about whether or not to isolate the Power transformer from the chassis. There seems to be a difference in opinions on the subject, so...
I raise the transformer on Kenwood KT-7500 tuners as a standard during the mod process. It usually drops the AC voltage standing on the chassis a few volts....
Do you ground the transformer frame to the star ground after raising it or do you keep it totally isolated. Also, do you orient the AC in to minimize the stray...
Jim, This is a newby question but I'll ask it anyway because I always wondered about this. When you say you electrically isolate the transformer do you mean...
On the Kenwood KT-7500s. About 30 of them now and I'm tired of doing them. The trannie is totally isolated (physically and electrically ) and the two AC input...
I was lucky enough to shop at the same mom and pop store as Camille and they HAD 3/4 inch rubber stand offs with a screw coming from one end and a nut embedded...
If those rubber standoffs work, I would suggest drilling the transformer mounting holes larger and use rubber gromments. That way the bolts are still through ...
-Hi Roger, Jim and gang, You can get those rubber sandwich mounts Jim describes from McMaster- Carr. # 9376K142. These are 5/8" dia. X 1/2" high with # 8-32...
Hi: I just about came up out of my chair upon seeing the ampex preamp posed outside in someone's garden! I have one just like it; having used it since around...
Yep, I put to photo up because I have it for sell on eBay. My eBay pics make it look bluish. So when someone asked, I took it outside for a better photo. It...
Jim: On the inside of one of the cover plates is a tube chart. It shows a 12AU7 in the output position; all others are Xs. The final stage as you now doubt...
No, thanks for helping me out. The tube chart is no more but it was easy to trace back and find the output tube. I'll draw a chart for the new owner, if it...
I'm looking for upgrade information for the Crown IC150A and the DC300A units. Any info on substitute opamps and caps would be appreciated along with more...
