Turntables: 2 Tonearms. What do you Have or Know About?

Elliott - The plinth was made in Italy including the very well machined aluminum arm boards. the veneer is apple from Germany. Peter does some amazing plinths. He is a fellow member of San Diego Audio Guild…  a true renaissance man !

i am working on some Panzerholtz armboards….

best to you….. a fun and great thread…. 

@tomic601 Can you offer a assessment of your experience with Panzerholz.

I am a advocate of this material and encourage the use of it for audio purposes.

Kuzma Stabi R can accept upto 4 tonearms. This pic shows it with 3. 

sksos

that’s the 1st 4 arm TT I/we have seen here

from their web site

many variations shown there

’non flexible belt’.

.............................................

I have a vintage 1958 Viking 75 (telex) 2 track stereo Tape Deck (play only) that came out of my Uncle’s Fisher President II that I inherited. It has a ’non flexible flat belt’, the outer one of this set.

.............................................

Tape Deck was from the ’crossover’ era: ’In-Line’ or ’Staggered’.

This shows

1. an erase head left (both tracks); and

2. centered: an ’in-line head’ (both L and R tracks ’in-line’ vertically (the final 2 track/half track accepted version)

3. 3rd head, one track only,, to the right, further along (staggared)

...........................................

4. Deck had a switch:

a. ’in-line’ position used the center 2 track head for stereo playback, 3rd head disabled.

b. ’staggered’ position used one track from the centered head, and the other track from the single track head further along.

5. eventually ’staggered’ method lost and the 3rd staggered head was eliminated.

........................................

I have a small collection of 2 track stereo tapes, some marked ’in-line’ and some marked ’staggered’ that came with the Fisher Console. They are not 15 or 30, but Pre-Recorded 7-1/2 IPS. They sound fabulous.

I have been trying to find a settlement with the idea of a Cantilever Sidebar TA Mounting Arm Board.

The Bolt Down method commonly seen is simplistic and hopefully is not compromised as a design.

I have a design in place for one of my Panzerholz Plinths to receive a Cantilever Side Bar TA Mount, where I have attempted to avoid  the usually seen Bolt Down Fastening of the attachment.

My design which lends itself quite nicely to being done in P'holz, is a interference fit Mortice and Tenon with a Flange to receive retaining fastenings into threaded inserts placed into the main plinth, as well as having two threaded inserts, inset into the Side Bar flange to receive fastenings to help release the part when not wanting it attached. The idea is for there to be a few parts produced, to be exchangeable, enabling working with differing lengths of Tonearm.

Slots to be used for allowing setting up varying length TA's in Plinths or Arm Boards are something I have commenced avoiding quite a few years past, all leads back to the rigid coupling principles.

My last two produced Plinths have extremely tight tolerances machined into the Plinth to receive the TA that is now used.

The Producer of my most recent produced Plinth, has an identical dimension Plinth > TT > TA and they are settled with a Slot in their Plinth.

Each to their own when it comes to such subjects.

I will be in a position to learn if a sonic is affected between a Plinth Mounting and Side Bar Mounting a TA, I will be settling with that as the only goal.
